Abstract:
Controller structure of an electronically controlled suspension system utilizes two controller loops namely outer loop and inner loop controllers which corresponds to vehicle controller and actuator controller. This paper introduces a multi-order PI control for semi-active MR damper suspension system for the outer loop controller. In inner loop controller, a direct controller which assumes that the damper force produced by MR damper is directly proportional with the current applied to the damper coils is implemented. Simulation studies are performed on a quarter car model in both frequency and time domain simulation, whereas experimental study is conducted on a full scale quarter car test rig. The simulation and experimental results show that the proposed control scheme is able to provide significant improvement compared to its counterparts. The proposed scheme is also easy to realize in practice due to the simple structure.
