In order to improve the road handling and passenger comfort of a vehicle, suspension is provided. An active suspension is considered to be better than a passive suspension. In this paper, 2 degree of freedom model of quarter car active suspension system is designed, which is subjected to road disturbance. Due to the fact that strong nonlinearity inherently exist in the spring ,damper and actuator components, therefore nonlinear effects must be taken into account in designing the controller for practical suspension systems. Since parametric uncertainty in the spring, damper and actuator has been considered, therefore robust control is used. H∞and μ- synthesis controllers are used to improve the ride comfort and road handling ability of the car as well as to check the robust performance of the system. The results shows that both controllers give good performance, but μ synthesis controller has superior robust performance as compared to H∞ controller as well as settling time of body acceleration and suspension deflection is also minimum with μ synthesis controller.
