An algorithm for selecting the transfer function in the negative feedback circuit based on the mathematical model of electroelastic body is proposed for ensure stability conditions of the system shapes. A procedure for constructing a vector of correcting action in case of incomplete control is developed (system control by correcting action, which amount is less than the total number of freedom degrees of the system). To illustrate the proposed approach the parabolic shell with embedded piezoelectric actuators is demonstrated. The control actions role for the shape of deformed shell surface does an electrical potential on the electrodes of piezoelectric elements.
