| 摘 要： | 应用有限元方法建立了贴有压电驱动器的悬臂梁动力学模型,采用二次型最优控制理论建立控制规律,对悬臂梁在初始扰动和持续外激励作用下的振动进行了主动控制实验。实验结果表明,所设计的控制系统可以有效地抑制两种情况下悬臂梁的振动。

| Abstract: | A dynamical model for the cantilever girder glued with piezoelectric actuator is built,based on finite element method.With the theory of quadratic optimization control,the control law is established,and the experiments of active control for the cantilever girder,under the condition of initial disturb and continuous external force vibration,are made to show that designed control system can check the vibrations. |

| Keywords: | active control cantilever girder piezoelectric actuator finite element. |
