Comparison of PI, Higher order and First order of Auto Disturbance Rejection Controller for Induction Motor Drives
G. Mounika, M. Nagaraju
DOI: 10.17148/IJIREEICE.2016.4903
Abstract: A nonlinear auto disturbance rejection controller (ADRC) has been developed to ensure high dynamic performance of induction motors. Compared with the existing high-order ADRC-based speed control structures, the proposed method does not need to estimate the rotor flux. By using extended state observer (ESO), ADRC can accurately estimate the derivative signals and precise decoupling of induction motors is achieved. In addition, the proposed strategy realizes the disturbance compensation without accurate knowledge of induction motor parameters. The simulation and experimental results show that the proposed controller ensures good robustness and adaptability under modeling uncertainty and external disturbance. It is concluded that the proposed topology produces better dynamic performance, such as small overshoot and fast transient time, than the conventional proportional/integral (PI) controller in its overall operating conditions.

DOI: 10.17148/IJIREEICE.2016.4905
Abstract: Biometric systems have been researched intensively by many organization and institution. It overcomes the conventional security systems by identify “who you are”. This paper discusses the current image based biometric systems. It first gives some information about why biometric is needed and what should people look for in biometric systems. Several popular image based biometric systems have been examined in this paper. The biometric systems included are face, fingerprint, hand geometry, hand vein, iris, retina and signature. Biometrics is associated with the use of unique physiological characteristics to identify an individual. The application associate with biometrics is security. Biometrics identifies an individual by measuring their physical and behavioural uniqueness or patterns, and comparing it to those on records. Iris recognition is the most unique and effective one which provides maximum security. When the case of wearing a contact lens comes then the fault mismatch chances are high. Even if the person is true the presence of contact lens makes a mismatch in the person’s identification. For the proper identification there exist two sets of databases and they are IIIT-D database and ND-Contact Lens database. These two databases perform very well when compared with the other lens detection algorithms.

Adaptive Filtering Algorithm for Acoustic Echo Cancellation in Hands Free Communication System
Rashi Baraliya, Prof. Mugdha Dewasthale
DOI: 10.17148/IJIREEICE.2016.4906
Abstract: Acoustic Echo Cancellation (AEC) is a common occurrence in today’s telecommunication systems. It occurs when an audio source and sink operate in full duplex mode. In this situation the received signal is output through the telephone loudspeaker (audio source), this audio signal then gets echoed through the physical environment and picked up by the systems microphone (audio sink). The effect is the return to the distant user of time delayed and attenuated images of their original speech signal. The signal interference caused by acoustic echo is distracting to both users and causes a reduction in the quality of the communication. Here the focus is on the use of echo cancellation algorithm by making use of adaptive filtering techniques to reduce this unwanted echo, thus increasing communication quality. Adaptive Filters are a class of filters that iteratively alter their parameters in order to minimize a function of the difference between a desired target output and their output. In the case of acoustic echo in telecommunications, the optimal output is an echoed signal that accurately emulates the unwanted echo signal. This is then used to negate the echo in the return signal. The better the adaptive filter emulates this echo, the more successful the cancellation will be. Performance parameter of pro-posed algorithm will be analyzed using Echo Return Loss Enhancement (ERLE), Mean square Error (MSE), and Convergence Time.

DOI: 10.17148/IJIREEICE.2016.4908
Abstract: Moving object detection and tracking is one of the security application which has created a great interest for computer vision researchers due to its applications in areas, like video surveillance, traffic monitoring and image recognition. Moving object detection involves identification of an object in consecutive frames where as object tracking is used to monitor the movements with respect to the region of interest. In this research work GUI (Graphical User Interface) is created by using Guide in MATLAB which provides point-and-click control of software applications, eliminating the need to learn a language or type commands in order to run the application. In this paper object detection is performed by using background subtraction algorithm based on Gaussian mixture model that can handle large variations in the background intensity distribution and tracking in videos is performed by using kalman filter which uses a series of measurements observed over time, containing statistical noise and other inaccuracies, and produces estimates of unknown variables that tend to be more precise than those based on a single measurement alone, a bounding box is drawn around the object to track the moving object as the object moves in the video frames, the count value of number objects in every frame is displayed in MATLAB command window. Here MATLAB is interfaced with Arduino board (A microcontroller based board) which is connected with LEDs based on count value number of LEDs will glow. The count value from MATLAB is communicated with Arduino board through serial communication.

Abstract: In a generation where time is the greatest deciding factor, air travel is the most preferred means of transport. Air transport being the fastest means of transport is best suited for long distances travel within minimal time. Airports and airlines are the emerging global companies providing air services. With the added advantages of airlines and airports, travellers face the most common and annoying problem of luggage loss. The loss and mixing of luggage is the most awful experience faced by hundreds of passengers every day. Not much is done in this field to help out the passengers with the problems of suitcase/luggage mixing and loss. To help the travellers we have developed the concept of an intelligent suitcase. This intelligent suitcase is designed with the help of latest technology solving the problems of mixing and loss of suitcases at the airports. The suitcase works on the Bluetooth technology interfaced with a controlling unit, Gps/gsm modules, Rfid cards, ultrasonic sensors, power unit, load cell etc. The suitcase can be easily tracked for its location by the help of the gps technology and the Rfid cards help in the unique identification of the suitcase. It is controlled by the Smartphone of the passenger and the Bluetooth technology helps in digital locking, location tracking and identification along with many other specially designed features.

An Efficient Zadoff-Chu Based Communication System
Remya B, Ashish Francis, Vimal Raj V
DOI: 10.17148/IJIREEICE.2016.4910
Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation technique in which the subcarriers are orthogonal to each other. OFDM provides high data rate, resistance to multipath fading. OFDM provides an effective and low complexity means of eliminating inter symbol interference for transmission over frequency selective fading channels. OFDM is becoming widely applied in wireless communications systems like digital audio broadcasting (DAB) systems, digital video broadcasting (DVB) systems, digital subscriber line (DSL) standards, and wireless LAN standards. Signal to noise ratio is used as an indicator for evaluating the quality of communication. So it is very important to estimate the SNR value for the modern wireless communication. By introducing a specific pilot sequence built from ZC sequences, pilot can be used as synchronizing mechanism in time domain as well as channel estimation. In this paper OFDM Systems with Zadoff-Chu pilots is proposed. Also Selected Level Mapping (SLM) and Clipping and Filtering techniques have been used for Peak-to-Average Power Ratio (PAPR) reduction, since high PAPR of the transmit signal is considered to be one major drawback of OFDM systems. The proposed system can be used for providing better performance of the communication systems.

DOI: 10.17148/IJIREEICE.2016.4911
Abstract: In any Wireless Mesh network, an energy efficient routing protocol is the main field of concerns, as we know that nodes of the WMN works, based on the limited battery power, so routing protocol has to be designed in such a manner that it utilize minimum battery power and it routs data efficiently, which maximize the overall life time of the network. Many existing works shows the energy efficient protocol during the selection of cluster head (CH). In this paper we have proposed an energy optimized cluster head (CH) selection in a wireless mesh network dynamically. In proposed model we considered a protocol for the selection of cluster head, which is based on the maximum remaining energy and minimum draining rate of every node. The protocol predicts the most efficient node and based on that result it will select the cluster head dynamically and periodically, which will have sufficient energy and low depletion rate. The protocol will evaluate under static nature of the nodes. Simulation is carried out in Network Simulator-3(NS-3).

Modified Seven Level Inverter Integrated With Boost Converter
Greeshma Divakaran, Sooraj N.M
DOI: 10.17148/IJIREEICE.2016.4914
Abstract: Energy demand is increasing day by day. In order to meet this energy demand renewable energy sources have to be incorporated. Renewable energy sources like fuel cells, pv cells etc. produces DC voltage. But most of the house hold and industrial purpose require AC voltage. So this DC (direct current) voltage has to be converted into AC (alternating current) voltage. For this power electronic inverters can be used. Multilevel inverters has got wide spread acceptance as it can synthesis almost sinusoidal wave form. This paper presents an inverter which can give a seven level AC output without variation in its voltage amplitude, from a variable DC source. Here a boost converter is introduced as a front-end stage. This DC-DC conversion helps to stabilize the output voltage. A new class of multilevel inverter with coupled inductor was introduced in the second stage to get a seven level AC as output. The working principle of DC-DC converter and the inverter are explained. The circuit is tested with different DC voltage and found to give the same output voltage waveform. The circuit has been simulated using MATLAB/Simulink tool and a prototype is made to verify the validity and performance of the circuit.

Power Factor Corrected Zeta Converter Based Switched Mode Power Supply
Reshma Shabi, Dhanya B Nair
DOI: 10.17148/IJIREEICE.2016.4915
Abstract: Switched Mode Power Supply (SMPS) is an integral part of the computer that converts ac to multiple numbers of suitable dc voltages to impart power to different parts of the PC. It contains a diode bridge rectifier (DBR) with a capacitor filter followed by an isolated dc-dc converter to achieve multiple dc output voltages of different ratings. The uncontrolled charging and discharging of the capacitor result in a highly distorted, high crest factor, periodically dense input current at the single phase ac mains; this violates the limits of international power quality (PQ) standards such as IEC 61000- 3-2. Further, the neutral current in the distribution system increases if these PCs are used in large numbers which creates serious problems like overloading the neutral conductor, noise, de-rating of the transformer, voltage distortion etc. In this paper, a non isolated power factor corrected (PFC) converter is being proposed to be used at the front end to improve the power quality of an SMPS for a PC. The front-end converter is able to reduce the 100-Hz ripple in its output that is being fed to the second stage isolated converter.

A Non Isolated Single-Switch High Step-Up Converter with Low Voltage Stress
Anu Jose, Divya Haridas
DOI: 10.17148/IJIREEICE.2016.4916
Abstract: A non-isolated single switch high step-up converter with low voltage stress is presented in this paper. The converter is derived based on the conventional fly back converter. A clamping diode as well as a voltage doubler circuit is used in order to reduce the voltage stress across the switch and diodes. Another converter can also be derived by rearranging the components and adding a capacitor to the circuit. Since the converter has low voltage stress, lower voltage rated switch and diodes are used, which result in high efficiency with low conduction losses. The MATLAB simulation of the converter is done using 24V input voltage and 250V/125W output. The lower stress on the switch and diodes are verified by the simulation results.

DOI: 10.17148/IJIREEICE.2016.4917
Abstract: In this paper, a non-isolated bidirectional DC- DC converter is presented. The proposed converter consists of two boost converters to enhance the voltage gain. Four power switches are employed in the proposed converter which their body diodes are also used. Two inductors and a capacitor are also employed as passive components. The input current is divided to the inductors which causes the efficiency to be high. The voltage gain of the proposed converter is higher than the Conventional Bidirectional buck/boost Converter (CBC) in step-up mode. The simple structure of the proposed converter causes its control to be easy. The steady state analysis of the proposed converter is discussed in this paper thoroughly. The closed loop simulations are done in both bucks as well as in boost mode of operation. Also some modifications are done in the circuit to act this as both buck and boost converter at the same time. Finally, the proposed converter prototype circuit is implemented to justify the validity of the analysis.

Piyali Chatterjee, B Harikishor Rao
DOI: 10.17148/IJIREEICE.2016.4919
Abstract: The analysis of the plant diseases may involve the detection of the abnormalities introduced in the plant leaves, which may or may not be visible to the naked eyes. With the layman’s idea of the problems in plants, one cannot proceed with any random solution in the form of any pesticide or fertilizer, unless there’s a sheer and accurate understanding of the disease spots and proper pattern recognition which otherwise would lead to a catastrophic situation where besides the loss of the money, the plant will remain untreated and the diseases will also get more time to spread. In order to combat this situation effectively, an artificial intelligence technique has been employed in this paper using k-means clustering (segmentation). The work begins with image acquisition, image enhancement and restoration, and information extraction from images for further computer analysis.

DOI: 10.17148/IJIREEICE.2016.4922
Abstract: In this paper we experimentally evaluate a software solution for fast, accurate and automatic detection of plant diseases through Image Processing. Identification of the plant diseases is the key to preventing losses in the quality and quantity of the agricultural product. Health monitoring and disease detection of plant is critical for sustainable agriculture. The typical method of studying plant disease is to rely on visually observable patterns on the plant leaves. Visually identifying plant diseases is inefficient, difficult, time consuming, requires expertise in plant diseases and continuous monitoring which might be expensive in large farms. Therefore; a fast, automatic and accurate method to detect plant disease is of great importance. Hence, image processing technique is employed for the detection of plant diseases. The implementation of these technologies will lead to improved productivity.

Ajmal Ahmed N, Thanuja Mary Abraham
DOI: 10.17148/IJIREEICE.2016.4924
Abstract: A hybrid boosting converter (HBC) with collective advantages of regulation capability from its boost structure and gain enhancement from its voltage multiplier structure is proposed in this paper. The new converter incorporates a bipolar voltage multiplier, featuring symmetrical configuration, single inductor and single switch, high gain capability with wide regulation range, low component stress, small output ripple and flexible extension, which make it suitable for front-end PV system and some other renewable energy applications. The operation principal, component stress, and voltage ripple are analyzed in this paper. Performance comparison and evaluation with a number of previous single-switch single-inductor converters are provided. Fuzzy Controlled closed loop of the proposed converter is studied and simulated A 3.5 to 35 V second-order HBC prototypes was built. The experimental results confirm the feasibility of the proposed converter.

A Double Quadratic Buck Converter
Lismy K Muhammed, Jubin Eldho Paul
DOI: 10.17148/IJIREEICE.2016.4925
Abstract: The Double Quadratic Buck Converter is a new non-insulated DC-DC converter. This new converter is characterized by average output voltage to be lower than input voltage, and the voltage intermediate capacitor also to be lower than the input voltage. It has the advantages of high gain ratio near half range of duty cycle compared to the conventional Buck Converter. In this case, the voltage at the switches is lower than the input voltage and half the voltage in the switch of the existing Quadratic Buck Converter. That means in double quadratic buck converter, the stress voltage over the switches is reduced to half of the value compared to the conventional Quadratic Buck Converter. The topological symmetry simplifies the theoretical analysis of the converter .The converter operation stages with the respective waveforms are explained and closed loop simulation of the new converter is done.

DOI: 10.17148/IJIREEICE.2016.4926
Abstract: The aim of this study is to develop a high-efficiency single-input multiple-output (SIMO) dc–dc converter. The pro- posed converter can boost the voltage of a low-voltage input power source to a controllable high-voltage dc bus and middle-voltage out- put terminals. The high-voltage dc bus can take as the main power for a high-voltage dc load or the front terminal of a dc–ac inverter. Moreover, middle-voltage output terminals can supply powers for individual middle-voltage dc loads or for charging auxiliary power sources (e.g., battery modules). In this study, a coupled-inductor- based dc–dc converter scheme utilizes only one power switch with the properties of voltage clamping and soft switching, and the cor- responding device specifications are adequately designed. As a re- sult, the objectives of high-efficiency power conversion, high step- up ratio, and various output voltages with different levels can be obtained. Some experimental results via a kilowatt-level prototype are given to verify the effectiveness of the proposed SIMO dc–dc converter in practical applications.

DOI: 10.17148/IJIREEICE.2016.4927
Abstract: In this paper, a Bit Error rate analysis is presented for multiple-input–multiple-output (MIMO) system with two way multiple relay system with amplify and forward (AF) considered in QPSK modulation technique, where a transmitted signal consists of a pre-coders followed by an space–time block code (STBC), such as dirty paper code (DPC). DPC primarily helps transmit data efficiently even though the communication channel offers interference. Its objective is always to send as much readable information on a channel with interference as you can. The BER performance of this method is compared with the pre-coder based methods like Minimum Mean Square Error (MMSE) and zero-forcing beam forming (ZF-BF). This paper considers both one-way and two -way relaying systems with multiple relays between two terminal nodes where all nodes have MIMO antennas. Simulation effects we advise a fresh practical scheme leads with low computation complexity and BER performance and faster convergence with better system utilization.

Phase Shifted Semi Bridgeless AC DC Converter

DOI: 10.17148/IJIREEICE.2016.4928
Abstract: A Plug in hybrid electric vehicle is a hybrid vehicle with a storage system that can be recharged by connecting a plug to an external electric power source. The charging ac outlet inevitably needs an onboard ac dc charger with power factor correction. The two stage approach with cascaded PFC ac–dc and dc–dc converters is the common architecture of choice for PHEV battery chargers, where the power rating is relatively high, and lithium ion batteries are used as the main energy storage system. In the two stage architecture, the PFC stage rectifies the input ac voltage and transfers it into a regulated intermediate dc link bus. At the same time, PFC is achieved. Phase shifted semi bridgeless ac dc converter is proposed to simplify the current sensing technique for semi bridgeless PFC converter. The converter features high efficiency at light loads and low ac input lines, which is critical to minimize the charger size, charging time, and amount and cost of electricity drawn from the utility. The converter is ideally suited for residential charging applications.

Abstract: This paper presents a comparative performance analysis among different positive feedback based match line (ML) sensing scheme such as Mismatch dependent, Active feedback and Resistive feedback scheme. The comparison has been done based on parameters like search time, voltage margin, peak dynamic power and worst case energy consumption. Although most popular ML sensing scheme Current Race (CR) consumes more power than positive feedback based ML sensing scheme but performance comparison has also been shown between CR with each of three positive feedback based match line (ML) sensing scheme for equal search time. Finally, for search time Resistive feedback, for voltage margin and peak dynamic power consumption Mismatch dependent and for worse case energy consumption Active feedback scheme were found to be showing the best performance. For performance comparison the all the circuits is simulated using 130nm 1.2V CMOS logic.

Half Bridge Circuit for Single Phase Active Power Decoupling
Mr. Malvatkar Sunil Dashrath, Mr. K.V. Rammohan
DOI: 10.17148/IJIREEICE.2016.4934
Abstract: Single-phase ac/dc or dc/ac systems are inherently subject to the harmonic disturbance that is caused by the well-known double-line frequency ripple power. This issue can be eased through the installation of bulky electrolytic capacitors in the dc link. Unfortunately, such passive filtering approach may inevitably lead to low power density and limited system lifetime. An alternative approach is to use active power decoupling so that the ripple power can be diverted into other energy storage devices to gain an improved system performance. Nevertheless, all existing active methods have to introduce extra energy storage elements, either inductors or film capacitors in the system to store the ripple power, and this again leads to increased component costs. In view of this, this paper presents a symmetrical half- bridge circuit which utilizes the dc-link capacitors to absorb the ripple power, and the only additional components are a pair of switches and a small filtering inductor. A design example is presented and the proposed circuit concept is also verified with simulation and experimental results. It shows that at least ten times capacitance reduction can be achieved with the proposed active power decoupling method, and both the input current and output voltage of the converter can be well regulated even when very small dc-link capacitors are employed.

Manoj Siva Kumar K, Jayadurga B
DOI: 10.17148/IJIREEICE.2016.4935
Abstract: This paper proposes a topology of a cascaded multilevel inverter that utilizes less number of switches than the conventional topology. Therefore with reduced number of switch count topological structures configured in the form of a matrix for a cascaded Multi level inverter (CMLI). As the numbers of switches are reduced, both conduction and switching losses will be decreased and electromagnetic interference is reduced, which leads to increase the efficiency of converter. The proposed inverter focus extends to produces number of voltage levels in the same number of the voltage source and reduced number of switches compared to the conventional inverters. Thus the inverter will be simulated with the implementation of appropriate pulse width modulation (PWM) techniques strategy to generate firing pulses and ensure the desired operation of the power modules techniques and its effect on the harmonic spectrum will be analyzed. The system will be modeled with the help of MATLAB/SIMULINK
