【Abstract】 A finite element formulation for vibration control of a larminated plate with piezoelectric sensor/actuators is presented. Hamilton’s principle is used to formulate the electromechanical coupled dynamic system equations for the overall structure. Finally, the constant-gain negativevelocity and Lyapunov feedback control algorithms are applied to control the structural vibration.更多还原
