摘要
针对具有刚性运动基的柔性板结构的振动主动控制进行了研究。建立了包含压电机敏元件的、具有刚性转动体与二维柔性板的、刚柔耦合系统的振动数学模型;获得了系统的状态方程、传感方程与反馈控制方程,根据输出反馈控制原理,求得了反馈增益矩阵,在此基础上进行了实验研究,实验结果证明了理论研究的合理性和有效性。
A study on active vibration control of a flexible plate on rotaing rigid base is presented in this paper. The system equation, including state equation, sensing equation and controlling equation is derived. The experimental setup with a flexible plate mounted on rotating rigid base is presented. Based on the principle of output feedback control, the feedback gain matrix is determined according to the experimental system. Experiments were carried out to verify the theory. The experimental results showed that the principle of active vibration control for the flexible plate on a rotaing rigid base is reasonable and valid.
