| 摘 要： | 通过两自由度系统讨论速度反馈在振动主动控制中的作用，原则上，速度反馈相当于改变系统的粘性阻尼矩阵，而受控系统的振响应则与改变后的当量系统的振动响动相同，研究结果以显表达式和曲线形式给出，说明受控系统的固有振动频率和阻尼是如何随控制力系数的改变而变化的。

| Abstract: | The action of velocity feedback on active vibration control in a system with two degreesof freedom is discussed in the present paper. Principally. the velocity feedback plays the roleof altering the viscous damping matrix of the vibration system. and the vibration response ofthe controlled system is the same as that of the equivalent sestem. The results are illustratedby explicit expressions and curves to show how the natural frequencies and damping of thecontrolled system vary with the change of the controlling force coefficients |
