A feasibility study examining the application of variable structure control on an active vehicle suspension system is presented in this paper. Specifically, sliding mode control is applied in a model-following context such that a limited- bandwidth active suspension emulates the behaviour of a skyhook damper.
Simulation results, obtained using a quarter vehicle model, indicate that the investigated active suspension controller can enable ride performance benefits and enhanced load disturbance rejection capabilities. Moreover, it is shown that this controller can assure effective performance despite parametric and structural uncertainty.
