Abstract

In this paper, we propose a constrained H controller design method for the active suspension systems (ASS) with aperiodic sampling. The ASS are controlled by a hydraulic actuator which is usually limited by physical constraints. To utilize the information of saturation level, we express the ASS as the linear parameter varying (LPV) system by adopting time-varying parameters which depend on the constrained input. For the implementation of digital controllers, we consider the sampled-data H control. The stabilization condition is derived by using looped functional approach. The proposed controller guarantees the desired performance of the ASS despite of aperiodic sampling and input saturation. To demonstrate the validity of the proposed method, the simulation results are compared with the case of passive suspension systems.
