In the design passive suspension systems, there is a trade-off between the performance under bump input and that under high frequencies input due to high speed driving. In this work, a reference-model following sliding mode control (RMF-SMC) is proposed for active suspension systems in order to obtain high-performance suspension and vibration isolation in the frequency range that causes bad effects on human. In the proposed control algorithm, a sliding surface is defined based on the ideal skyhook dynamic such that the system exhibits its good suspension and vibration isolation characteristics once the system enters the sliding mode. Computer simulations are implemented to evalute the effectiveness of the proposed control algorithm.
