バングバング・アクチュエータによる柔軟構造物の振動制御について : 第1報,柔軟はりモデルを用いた数値シミュレーションによる基本特性の評価

抄録

This study is concerned with basic characteristics and control performance of a bang-bang actuator. The bang-bang actuator studied here is a proof-mass type which is controlled by on-off command. The major advantage is that it can be made to be light in weight and low in energy consumption. Moreover, it does not require a servo-amplifier for each actuator and the number of actuators can be made large, so that it is suitable for distributed control. The analysis model is a flexible beam on which one or more bang-bang actuators is placed. It has been confirmed that the performance is approximately twice as effective as that of a tuned passive damper and nearly equal to that of a proof mass actuator under direct velocity feedback control. Moreover, it has been shown that vibration suppression by bang-bang actuators has definite advantages in energy consumption and robustness over conventional methods.
