Abstract: Considerable amount of research has been carried out on active vehicle suspension control during the last few decades, basically using optimal linear quadratic regulators. Effect of time delay has been neglected most of the time or availability of preview information has been assumed. In this paper a discrete predictive method is formulated and time delay as an inherent characteristic of active systems is also taken into account. Preliminary results show that the proposed method, compared to passive suspension, is capable of reducing the RMS body acceleration and also suspension deflection for low frequency road disturbances, even in the presence of time delays. For higher frequency road inputs, however, the acceleration response degrades while the maximum suspension deflection is still controlled better than passive system.
