Abstract
A method of controlling deflection of a dynamic surface having a predetermined shape includes sensing a change in the predetermined shape of the dynamic surface, providing at least one piezoelectric actuator in communication with the dynamic surface for applying a counter force thereto, and activating the at least one piezoelectric actuator for applying the counter force to the dynamic surface for returning the dynamic surface to the predetermined shape.
