摘　　要：对一个带有压电铺层的悬臂层合板进行了振动主动控制的分析和试验。不但采用了速率反馈 ,还用现代控制理论的设计方法研究了最优控制问题 ,设计了相应的数字式控制试验系统 ,进行了试验验证 ,并对 2种控制律的结果进行了比较。Analysis and experiments of the active vibration control to a plate with piezoelectric actuators were summarized. The piezoelectric laminated plate was described. Both velocity feedback and linear quadratic Gauss control were analyzed and tested. The flow chart of optimal control law design was presented. Digital control systems were designed and tested. The curves for velocity auto-spectra of open-loop and closed-loop experiments were plotted. Calculating and testing results were compared. The effect of mechanical-electrical coupling was investigated.
