This paper presents a new approach of controlling the stationary response of a half car vehicle model traversing a rough road with constant velocity with semi-active MR damper suspensions. The MR damper performance is sought to be enhanced to that of the performance of active suspensions with H(infinity) control without and with preview. A method to determine the weighting factors in the performance index in Hinfinity control using a multi-objective optimization procedure is presented. The multi-objective optimization problem is solved by the NSGAII genetic algorithm in combination with Pareto optimal scheme. The equivalent linearization method is used to get the response of the vehicle with MR damper which is modelled by the modified Bouc-Wen model. Results show that the performance of the MR suspension improves with preview information and better than the performance of the passive suspension. The performance of the MR damper suspension with respect to sprung mass acceleration and pitch acceleration do not measure up to the corresponding performances of active suspension with Hinfinity control without and with preview. The suspension stroke and road holding performances especially at the rear are almost as good as the performances of the active suspension with Hinfinity control without and with preview. In certain cases the MR damper does not perform as well as the Hinfinity control with respect to road holding at the rear suspension.
