Adaptive Dynamic Surface Control of a Half-Car Active Suspension Systems with Hydraulic Actuator

In this paper, an adaptive dynamic surface control (DSC) strategy is proposed for a half-car active suspension systems (ASSs). The controller of the adaptive DSC technique is designed to stabilize the vertical motion and pitching motion of a car-body. In this case, ride comfort and handling stability can be significantly improved by the hydraulic actuator of ASSs. In addition, the DSC approach can eliminate the problem of “explosion of complexity” in the traditional backstepping-based designs. Finally, a simulation is performed for a servo system with hydraulic actuator to demonstrate the reliability and effectiveness of the proposed control strategy.
