同时采用被动和主动控制方法来抑制结构的振动，可以利用两者的优势以达到更好的控制效果。以粘弹性阻尼器和压电晶体作动器为被动和主动控制元件，建立了主结构与控制元件一体化的复合结构运动控制方程，以平面桁架结构为例进行了数值分析，研究了控制器设计和系统参数选择、主动振动控制的效果以及被动振动控制与主动振动控制的相互影响等问题
At the same time using passive and active control methods to suppress the structure of the vibration, you can take advantage of both to achieve better control. The viscoelastic dampers and piezoelectric crystal actuators are used as the passive and active control elements. The motion control equations of the composite structure with the main structure and the control elements are established. The planar truss structure is taken as an example for numerical analysis. The controller Design and system parameter selection, the effect of active vibration control and the interaction between passive vibration control and active vibration control
