Comparative study on the speed of DC motor using PID and FLC

The main purpose of this paper is to control the speed of a DC motor using two techniques, via PID Controller and Fuzzy Logic Controller (FLC). A system model is implemented for PID and FLC controllers along with a model for a DC motor using MATLAB Simulink. The performance of the two techniques is evaluated and compared in terms of the settling time (Ts) and maximum overshoot under different load conditions. PID controller is shown to give a good response and small rise time, but higher overshoot and settling time. Fuzzy Logic Controller is found to provide better performance as compared to PID controller in terms of settling time and percentage overshoot and a better control of the DC motor due to the fact that FLC required no tuning and human manipulations are reduced.
