In this paper, the applicability of the semi-active control system including the magneto-rheological fluid (MR) damper to the wind-induced vibration of the base-isolated structure is analytically studied. The proposed system consists of a MR damper and an aerogenerator. The control system operates without any computes, so that quite safe control can be done under severe conditions. The system aims at reducing the deflection of the isolator during strong winds by means of controlling the resistance force of the MR damper in accordance with generated electric power. A series of response analyses using simulated seismic and wind waves were carried out. It was confirmed that the proposed system is quite effective without any bad influences on the effect of the isolator.
