This paper describes about a controller design for a smart structure with a self-maintenance. A method of achieving self-sensing actuation without a bridge circuit is proposed in this study. Dynamics of this proposed system can be described as the state space expression with a direct transmission component. This means that the problem of balancing the bridge circuit is equivalent to the system identification and state estimation problem. The sub-space state space identification method is adopted a numerical algorithm of the system identification. Gain-Scheduled controller using a identified a direct transmission component as a scheduling parameter is proposed in this paper. The proposed method was verified with experimental results, demonstrating that smart structures can achieve self-maintenance by adopting a gain scheduled controller.
