Abstract

This paper presents an LMI based fixed-order controller design for quarter car active suspension system in order to ensure ℋ_∞ performance and the stability in the predefined D-Region. The simulation results and dynamic response of the real system show the effectiveness of the proposed method over improvements on ride comfort. The proposed low-order controller is compared with full-order one in simulation and application phases. The advantages of using low-order controller contrary to high-order one are discussed.
