A Comparative Study on Different Speed Control Methods of D.C. Drives for Electric Vehicle

Juhi Nagpal, Rahul Agarwal, Manish Shah


This paper describes a comparison of closed loop speed control of a separately excited DC motor using IGBT Chopper with the help of Fuzzy logic controller (FLC) and MATLAB / Simulink. In many industrial applications, conversion of constant voltage DC source into a variable voltage or variable current for the speed control of DC motor is required. For such type of operation a converter is used known as chopper. This paper explains the development of PI controller and a fuzzy tuned PI controller for speed control of DC motor. The simulation results are presented and analyzed in this paper.
