인체진동모델을 이용한 ER 시트 현가장치의 슬라이딩모드 제어 = Sliding Mode Control of ER Seat Suspension with Whole-Boby Vibration Model

다국어 초록 (Multilingual Abstract)

This paper presents robust control performance of a semi-active ER(electro-rheological) seat suspension. A cylindrical type of ER seat damper is designed and manufactured for a commercial vehicle. The governing equation is derived from 6-DOF seat-driver model and the obtained seat-driver model is reduced through balanced model reduction. A sliding mode controller is then designed with full-order state observer and experimentally realized where a driver is sitting on controlled seat. Control performances are evaluated in both time and frequency domains. In addition, comparative work between ER seat suspension and conventional passive suspension is undertaken with ride quality criteria.
