摘要：
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.
