Abstract

This paper analysis the performance of Fuzzy PD+I and conventional PID controller on nonlinear systems. The nonlinear systems used are level control of a surge tank and cart pole system. Level control of a surge tank level system and angular position of cart pole system have been tracked using Fuzzy PD+I controller and conventional controller. Four type of membership functions Bell, Pi, Gaussian and Psigmoid are used in the fuzzy PD+I control of the nonlinear systems. Effects of different membership functions on the systems control have been compared with conventional PID controller. For four different membership functions besides control performance stability criterion also have been implemented using phase-plane method.
