443 運動エネルギーによるパッシブ・可変アクティブ切り替え制御

抄録

Switching vibration control between dynamic absorber and active control has been proposed for the dual structure vibration device on the basis of the kinetic energy as the threshold. For the active control with a fixed feedback gain, the threshold should be set conservative and the effect of the active control was not enough. Therefore, a variable feedback gain is introduced, which is assumed the kinetic energy as an indicator. It is expected that the actuator moves in a mobile range as possible and the performance will be better than the conventional switching control. In this paper, the effective variable feedback and switching are considered by experimental results.
