推导了多层压电圆柱壳的运动方程和集成压电传感器的运动方程。采用模态展开法求解运动方程得到状态方程。将反馈控制方法、前馈控制方法及其组合作为混合控制方法应用于集成传感器和执行器的压电圆柱壳的受迫振动控制。仿真和实验结果表明，采用集成压电传感器和执行器结合混合控制方法可以获得良好的控制效果。
Equations of motion for multi-layer piezoelectric cylindrical shells and the equations of integrated piezoelectric sensors are derived. The state equation is obtained by solving the equations of motion with modal expansion method. The feedback control method, feedforward control method, and their combination as a hybrid control method are applied in the control of forced vibration of the piezoelectric cylindrical shell with integrated sensors and actuators. The simulation and experimental results show that good control effectiveness can be obtained by using the integrated piezoelectric sensors and actuators in conjunction with the hybrid control method.
