The main goal of the paper is to examine and optimize the parameters of a closed loop controller for a quarter car suspension model equipped with a semi-active magnetorheological damper. An ascillating vehicle model excited by perturbations of the ground and driving maneuvers is investigated. A quadratic quality criterion is assumed and minimized for an appropriately chosen sequence of the parameter values. In this way a trade-off between driving comfort and road holding capability is achieved. To emphasize advantages of the optimized LQR controller the car model behaviors under two different controllers: passive and hybrid are compared.
