摘要
利用有限元方法模拟压电结构的振动控制．从Hamilton理论出发推导出具有压电传感器及激励器的层合板的机电耦合动力方程．应用Lyapunov及负速度反馈控制算法来实现振动的控制．
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.
