The main function of the vehicle suspension is to improve ride and handling performance. In vehicle active suspension better ride comfort is usually required larger control input and larger suspension deflection. However the actuator that deliver the control signal have a limitation which is commonly known as actuator saturation. There is also a structural constraint that limits the suspension deflection. In this study an alternative approach to the vehicle active suspension system is proposed. In this approach some separation in the controller such that one part is devoted to achieve nominal performance and the other part is devoted to constraint handling is performed. In addition the actuator power consumption of the proposed control strategy is further investigated numerically. The simulation results show that the proposed control strategy can manage the trade-off between performance and the actuator power consumption.
