Fuzzy I-PD and fuzzy PID control of non-linear systems

This paper presents the comparison of tracking control performance of fuzzy I-PD Controller with fuzzy PID and conventional PID controllers. In this the Fuzzy I-PD controller composes of Mamdani fuzzy I and Mamdani fuzzy PD controllers and is adjusted to meet the desired control system performances both in transient state and steady state. Computer simulations are done for controlling the nonlinear systems by using fuzzy I-PD, fuzzy PID and the conventional PID controller are shown in this paper. The effectiveness of fuzzy controllers over the conventional controller are shown by choosing triangular, trapezoidal, gbell, gaussian and pi input fuzzy sets.
