Abstract
This paper shows a method of an active seismic feedback control of structure. To take into account the time delay of control force, kalman filtering prediction algorithm is used for the prediction of mode response in a multi degree of freedom system. The relation between the characteristics of sturucture and the precision of prediction was examined by caluculating a single degree of freedom system. Simulation analysis was used to clarify the usefulness and the characteristics of the proposed method. It is concluded that the proposed method has effective control efficiency than a system not taking account of time delay of control force.
