Fuzzy PID controller simulation for a quarter-car semi-active suspension system using Magnetorheological damper

Abstract

A quarter-car dynamic system has been modeled using Magnetorheological (MR) damper and a parallel structure of fuzzy PID controller to control the semi-active suspension system. The polynomial model is applied to estimate the behavior of MR damper. The MATLAB software and its Simulink environment are used to simulate the model of the system. The results show the use of fuzzy PID controller has successfully reduced the chassis displacement as the driving comfort objectives than PID controller and improved its robustness.
