Optimal Control Design of Automobile Suspension System Using Singularly Perturbed discrete-time systems

In this paper the controller design for vehicle suspension systems, based on a half-car model, using singularly perturbed discrete-time systems at steady state is considered. this strategy is based on the slow and fast subsystems controller design. The suspension system performance is optimized with respect to ride comfort ,tire deflections and front and rear suspension travels. Numerical simulations in discrete-time evaluate the performance of the active suspension systems.
