Design and Simulation of Speed Control of DC Motor by Fuzzy Logic Technique with Matlab / Simulink

The design of intelligent control systems has become an area of intense research interest. A promising direction in the design of intelligent systems involves the use of Fuzzy logic controller to discover the abilities of intelligent control systems in utilizing experience via rule-based knowledge. The most commonly used controller in the industry field is the proportional plusintegral-plusderivative (PID). PID controller requires a mathematical model of the system while Fuzzy logic controller (FLC) provides an alternative to PID controller, especially when data are not available or partly available for the system. For comparison purpose, three controllers PI, PID and FLC have been designed and implemented in the MATLAB/Simulink model to examine the performance of DC motor with different loads. The results show that the FLC give better response compared to PI &PID controller.
