In this paper our proposed design method of a gain-scheduled controller is verified for vibration control of a multi-degree-of-freedom structure by using of an active dynamic vibration absorber with actuator constraints. We formulate the linear parameter varying system taking account of both the maximum control input and the maximum stroke of the actuator by using nonlinear functions of hyperbolic tangent. As the feedback signals of the gain scheduled control system we use the relative displacement of the primary structure or the acceleration of that as well as the stroke of the auxiliary mass. From the experimental results, it is shown that the closed-loop system has good performance even if saturation phenomena of the actuator occur against not only an impulsive disturbance but also the nonstationary random disturbance such as earthquakes.
