Abstract

A reasonable mathematical model of semi-active suspension is established based on a quarter vehicle. A fuzzy controller is proposed and its fuzzy rules are deduced using Matlab Fuzzy logic control toolbox. Simulation model for the whole system is completed by means of Matlab/Simulink. The response curves under random road profile excitations of semi-active suspension are given, which are compared with those of passive suspension. The comparison show that the body vertical acceleration is reduced obviously by way of using fuzzy control on semi-active suspension, meanwhile, the vehicle ride comfort and handling stability is improved.
