Summary:To provide a resonance suppression control device which suppresses and controls vibrations at a resonance frequency of a control target, the device being capable of robustly suppressing vibrations.SOLUTION: A control device 2 suppresses and controls vibrations at a resonance frequency of a control target P. The control device 2 includes: a feedback group 10 having a control unit 20 with a function as a band pass filter, a phase compensation unit, and an amplitude adjusting unit and determining an operation amount u of the control target P by negatively feeding the output of the control target P back to an input side; and a transfer function update unit 30 for updating the denominator R and the numerator S of a transfer function of the control unit 20 of the feedback group 10 according to an operation unit u and an output unit y of the control unit P.SELECTED DRAWING: Figure 3 【課題】制御対象の共振周波数における振動の抑制制御を行う共振抑制制御装置において、振動をロバストに抑制可能な構成を提供する。【解決手段】制御装置２は、制御対象Ｐの共振周波数における振動の抑制制御を行う。制御装置２は、バンドパスフィルタ、位相補償器及び振幅調整器の機能を有する制御部２０を有し、制御対象Ｐの出力を入力側に負帰還させることにより制御対象Ｐの操作量ｕを求めるフィードバックループ１０と、制御対象Ｐの操作量ｕ及び出力ｙに応じて、フィードバックループ１０の制御部２０の伝達関数の分母Ｒ及び分子Ｓを更新する伝達関数更新部３０と、を有する。【選択図】図３
