- 制振制御対象となる構造物に対し、往復動可能なAMD稼働マスと、前記構造物の振動動作を検出するセンサ、前記AMD稼働マスを駆動するアクチュエータ、前記アクチュエータを制御する制御部、を含む構成要素を具備して構成されるAMD装置であり、
前記制御部は、前記構造物に対して理想的な調整を行ったTMDの仮想モデルを有し、前記センサによって実測された前記構造物の振動動作を入力として前記仮想モデルに入力した場合の応答を用いて、前記アクチュエータへの指令信号を生成する事を特徴としたAMD装置。 - 前記構造物に対して理想的な調整を行ったTMD装置を仮想上に用意し、センサによって得た前記構造物の振動データから、動力学シミュレーションによってマス動作を計算するとともに、この時、前記TMDは制御対象に対して理想的な振動抑制力となるマス反力を与える動作を行って、前記TMDマス動作に対して、TMDマス・AMDマス質量比を乗じた動作をAMDに追従させることによって、力制御を行わずに理想的なマス反力を発生させるように構成した制御器を具備しこれを制御器として利用するようにしたことを特徴とする請求項1記載のAMD装置。
- 前記構造物の振動特性に対して、理想的な調整を行ったTMDの動力学モデル、動力学モデルと前記構造物の実測データによって得られたTMDマス動作を、TMDマス・AMDマスの質量比及びAMD装置の有するハードウェア上の制約に基づき、AMD動作指令値へと変換する指令値生成部、を含むことを特徴とする請求項1又は2記載のAMD装置の制御プログラム。
