To provide a vibration control system that can effectively control vibration, and to provide a structure, a marine vessel, a vibration control method and a vibration control program.SOLUTION: A vibration control system includes: a piezoelectric element 5 provided in a predetermined member such as a blade 3 and converting vibration into a voltage; and a virtual impedance part 6 constituting a closed circuit by being connected to the piezoelectric element 5 and outputting a current so as to simulate a virtual impedance on the basis of the output voltage of the piezoelectric element 5, thereby controlling the blade 3 from vibrating.SELECTED DRAWING: Figure 3
【課題】効果的に制振を行うことのできる制振システム、構造体、及び船舶、並びに制振方法、並びに制振プログラムを提供することを目的とする。【解決手段】制振システムは、所定の部材として例えばブレード3に設けられ、振動と電圧とを変換する圧電素子5と、圧電素子5と接続されて閉回路を構成しており、圧電素子5の出力電圧に基づいて、仮想的なインピーダンスを模擬するように電流を出力する仮想インピーダンス部6とを備えており、ブレード3の振動を抑制する。【選択図】図3
