Simulation and Analysis of Brushless DC Motor Based on Sinusoidal PWM Control

Abstract: This Paper is Presented According to the Control Strategy of the Pulse Width Modulation Techniques. Sinusoidal Pulse Width Modulation (SPWM) is used for Simulation of Brushless DC Motor Drive. Also the Hall Sensors are used to Sense the Rotor Position. According to the Hall Signal of Sense from the Rotor we get Six Signals. By Comparing Reference Speed and Actual Speed we get Error signal, now this Error Signal is compared with the Triangle Wave Generator and finally we get Final Error Signal. By Adding Previous Six Signals with this Error Signal of output will get Six Pulse, the Generated Six Gate Pulse given into the Inverter Circuit. The Simulation software used for the same is MATLAB/SIMULINK.
