摘　　要：采用作者在上篇导出的压电耦合体动力学模型，给出了压电主动阻尼控制系统的设计方法；导出了压电耦合梁系统的作动方程和检测方程的显式表达式。以此为基础，以简单梁为对象，对压电检测器和作动器的性能、粘结层的影响、压电主动阻尼控制及压电主。The design method of piezoelectric active damping control is given and the explicit expressionsof actuating and sensing equations for beam like structures with discretely distributed piezoelectric ceramic elements are derived by using the analytical model developed previously by the authors. The behavior of piezoelectric ceramic sensors and actuators, the effect of attaching layer on measuring and control, piezoelectric active damping control, and dual control of piezoelectric active passive damping are investigated under laboratory through a simple beam model.
