The purpose of this paper is to analyze effect of skyhook, groundhook and hybrid control strategies on semiactive suspension system through computer simulation of quarter-car model in MATLAB/SIMULINK. The ride comfort and handling characteristics of suspension system were observed for step input. The performance of passive suspension system model was compared with skyhook, groundhook and hybrid controlled semiactive suspension system performance. The result shows that skyhook control will offer better ride and handling as compared to other controllers.
