An automotive active suspension system composes of a mechanical structure and a feedback controller. Conventionally, these two elements are designed sequentially, with the controller design subsequent to that of the mechanical structure design. The traditional design method cannot obtain the global optimum performances for the system. This paper presents an approach to integrate structural and control parameters optimization for an automotive active suspension system via LMIs, for the effectiveness of the proposed integrated optimization method to improve riding and safety performance was proved by simulation studies.
