This paper proposes a design method for semi-active vibration isolation control of a structure with a semi-active damper. 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 control based on the linear matrix inequalities is obtained so that the closed-system is stable and has good performance. By simulations it is verified that the semi-active damper system designed is effective in comparison with either a passive damper against a non-stationary random input such as earthquakes.
