In this thesis, the dynamic models of a specific precise instrument in spacecraft are established and an active vibration isolation system based on piezoelectric intelligent structures is constructed. theoretical analysis and numerical simulation on this system has been carried out. piezoelectric intelligent structure is applied to civil engineering. the piezoelectric intelligent control devise is used for the control of translation - torsion coupling responses of multi - story frame structure suffered from earthquake
本文還將壓電智能結構主動隔振的理論和控制方法應用到土木工程領域，利用一類壓電材料控制器對平移-扭轉耦聯的框架結構進行了主動隔震，模擬結果顯示：結構各層的平移和扭轉均得到顯著減小，表明將智能結構系統用於結構地震反應主動控制中的可能性。
