Control of non-linear systems using fuzzy PI-PD controller

Abstract

This paper gives the relationship of control performance of various types of fuzzy controllers, fuzzy (PI-PD) controller, combination of fuzzy PI and PD controller and fuzzy PI-PD controller. The analytical structures of Fuzzy PI-PD controller is deciphered through triangular memebership functions by using mamdani row interference technique and zadeh fuzzy logic and center of gravity defuzzification method. In simulation the control performance of non linear systems for various controllers by taking triangular, Gaussian g bell, trapezoidal memebership functions.
