This paper proposes a controller based upon H∞ control approach in order to improve the vehicle performance under two different road profiles. In this study, there are two control targets that they are car body travel and suspension deflection. In fact, H∞ controller is responsible for minimizing the infinity norm of two subsystems. The first one is from car body travel to road disturbance and second is from suspension deflection to road disturbance. These two control targets must be improved by a logical control input that is determined by H∞ control approach. In order to improve the performance of the quarter-car, weighting functions are also defined. Disturbance that is the system input is considered as two types of road profiles, harmonic and random. The results show that the H∞ controller is able to improve the quarter-car performance for both roads. In addition, the sensitivity analysis is done to show that the active suspension system is able to work when sprung mass changes as may be occurred when passengers added.
