MATLAB Simulation for Control System

Abstract: This paper presents the MATLAB simulation of control system and discusses open loop and closed loop properties of control system. In this paper we start with transfer function of control system and their pole zero plots to frequency response through MATLAB simulation coding. This paper also explains time domain and frequency domain response of control system to different-different input, frequency domain analysis three techniques like root locus, bode plot and nyquist plot are discussed. It is thus important to learn first how to generate transfer function and then applied MATLAB commands to them to applicable in control system analysis, which are the main objectives of this paper. A secondary objective is to learn the application of some basic MATLAB commands and how to apply them in simple control system problems.
