This paper proposes a design method for vibration isolation control of a semi-active suspension using MR damper. By using nonlinear functions we formulated the linear-parameter-varying system taking account of mechanical constraints such as valve stroke of the semi-active damper and the damping coefficient restriction. The gain-scheduled controller based on the linear matrix inequalities is obtained so that the closed-loop system is stable and has good performance even if saturation of the valve stroke occurs. By simulations it is verified that the semi-active damper system designed is effective in comparison with a passive damper. We then made a experimental setup which has an MR damper and investigated characteristics of the MR damper. Furthermore, we proposed the control method of the MR damper using the relation between input current and the damping coefficient.
