Fuzzy PID Controller: Design, Tuning and Comparison with Conventional PID Controller

In this paper, a fuzzy proportional integral derivative (PID) controller is proposed which can be tuned by carrying the tuning rules from PID domain to fuzzy domain. As a nonlinear controller can control a nonlinear process more efficiently, fuzzy controller can provide better performance in terms of rise time and smaller overshoot. The proposed controller is evaluated using some simulations. The simulation results show that both the transitory performance and the steady state performance are better than that of conventional PID controller
