转子振动的主动控制

本文针对转子振动主动控制中系统矩阵中含有陀螺阵这一特点,提出了在频域中的二次型目标函数;根据转子振动故障的特点,明确提出了转子振动主动控制的三个作用,研究了相应的控制器设计方法;并以一悬臂模型转子为例,分析了振动主动控制的可能实施方案及效果;结果表明,本文中所提出的方法效果良好,有重要应用前景。

Active Control of Rotor Vibrations

A quardratic objective function in frequency domain is presented in this paper under consideration of the speciality that a gyroscopic matrix exists in the system matrix. Three main functions of active vibration control of the rotors are indicated based on characters of vibration faults of the rotors. Respective design methods of controllers are described. A model cantilever rotor is analyzed to show how to realize these control methods and bow about the control effect. Results of analysis show that effect of the control methods suggested in this paper is pretty well, all of the methods have important perspective for application.
