予測型適応制御による可変剛性型制震システム : 制震構造の研究

抄録

The active adjustable stiffness system is a mechanical device with the ability to detune from the seismic ground motion. An adaptive control is newly adopted, in which an analytical observer predicts the optimal stiffness in each half cycle. From the results of a DIB analytical simulator, the control effect is evaluated as the isolation from the seismic dominant components and the cancellation of the resonant force by the seismic force. Some necessary control conditions and the required capacity of control devices are demonstrated.
