Abstract: In this paper design of active suspension in a half car model is presented. The idea of suspension has to improve the ride quality while maintaining good handling characteristics of three road distrubancences bump and hole, sine and random .it input have been applied to disturb the suspension system. Then PID controller for active suspension system of half car model has been simulated by using an analytical model within MATLAB SIMULINK software. Based on these three road disturbances, the performances of passive and active suspension system were investigated.
