Design of equivalent fuzzy PID controller from the conventional PID controller

Fuzzy controllers are nonlinear and it is more difficult to set the controller gains when compared to conventional controllers. This research paper proposes a design procedure for equivalent fuzzy PID controller from the conventional PID controller domain over to single loop speed control of DC motor. The idea is to start with a tuned conventional PID controller and replace it with an equivalent linear fuzzy controller. This is relevant whenever a PID controller is possible or already implemented. From the simulated results of MATLAB/SIMULINK, it is proved that the fuzzy controller improves the performance over conventional controllers.
