Fuzzy Logic Controller has gained wide popularity in the application of speed control for the DC motors. Their performance, with the auto tuning is desirable. In this project, the performance of a selected DC motor controlled by a Proportional Integral Derivative (PID) controller and Fuzzy Logic Controller are investigated. An overshoot speed is observed with an accompanied settling time thereby confirming the behavior of a PID controller and Fuzzy Logic Controller. It is therefore a matter of necessity to tune the Fuzzy Logic Controller in order to obtain the desired performance. On the other hand, a Fuzzy Logic Controller applied to the DC motor is investigated. With the application of appropriate expert rules, there is minimum overshoot and the settling time is within the desired value. With the Fuzzy Logic Controller, manual tuning is eliminated and intelligent tuning takes the centre stage with satisfactory performance. The speed control of the DC motor is performed using PID and FLC in MATLAB environment. The results show that the FLC approach has minimum overshoot, minimum transient and steady state error, which show more effectiveness and efficiency of FLC than conventional PID controller.
