| Abstract: | Analysis and experiments of the active vibration control to a plate with piezoelectric actuators are summarized. Both velocity feedback and linear quadratic Gauss(LQG) control were analyzed and tested. Digital control systems were designed and tested. Calculated and tested results are compared. The effect of mechanical electric coupling was also investigated. |
