对柔性梁的振动主动控制进行了研究.主动控制策略采用独立模态空间控制,模态控制律采用离散变结构控制律;给出了从实际测量中提取模态坐标和将模态控制力转换成实际控制力的方法,并给出了离散切换面和离散变结构模态控制律的确定方法.最后结合算例,对文中所给控制方法的有效性进行了验证.
The active vibration control of flexible beam is studied.The active control strategy adopts the independent modal space control, the modal control law adopts the discrete variable structure control law, the modal coordinates are extracted from the actual measurement and the modal control force is converted A method to determine the controllability of discrete control surfaces and the discrete variable structure modal control law is given.Finally, the effectiveness of the control method given in this paper is verified by an example.
