Robust H/sup /spl infin// controller design for performance improvement of a semi-active suspension systems

In this paper, a robust H/sup /spl infin// controller for semi-active suspension system is proposed. For the improvement of ride quality the robust H/sup /spl infin// controller is designed to satisfy robust stability and road disturbance attenuation using an H/sup /spl infin// control design procedure. The performances of the designed controller for some road conditions are evaluated by computer simulation and finally these simulation results show the usefulness and applicability of the proposed robust H/sup /spl infin// controller.
