Abstract: | The paper addresses the active damping of nonstationary vibrations of a hinged rectangular plate with distributed piezoelectric
actuators. The problem is solved by two methods: (i) the classical method of balancing the fundamental vibration modes by
applying the appropriate potential difference to the actuator and (ii) the dynamic-programming method that reduces the problem
to an algebraic Riccati equation. The results produced by both approaches are presented and compared
