From the energy point of view, the stability and controllability of the intelligent laminate with the piezoelectric sensing layer and the actuation layer attached are analyzed theoretically.The expression of the power flow reflecting the relationship between the energy change of the smart panel and the applied control voltage is derived Based on this, several properties about the stability of the smart board control system are obtained.The paper analyzes several uncontrollable situations of the rectangular board when controlling the board by using the whole actuation layer and applying a uniform voltage, The improvement of the controllability of the piezoelectric actuator is also discussed.
