为了有效抑制电磁轴承支承转子的周期性振动
研制了一种结构为重复控制和比例-积分-微分(PID)控制相结合的混合控制器.该混合控制器不仅保证了磁轴承的动态特性
而且消除了系统中的周期性扰动.通过讨论重复控制器的增益系数、截止频率对磁轴承的响应速度、稳定性的影响
给出了控制器的设计过程和参数整定方法.采用高速磁悬浮电机对磁轴承的性能进行了试验
试验结果表明
该控制器具有良好的动态特性
可有效地抑制电磁轴承-转子系统的周期性振动
并减少了转子频谱中的三倍频成分
从而提高了电磁轴承的支承精度.
To efficiently suppress the rotor periodic vibration in rotating mechanism
a controller combining PID control and repetitive control is presented for an active magnetic bearing(AMB). The PID controller ensures the system dynamic response
and the add-on type repetitive controller effects of removes the periodic disturbance from the rotor vibration. The effects of proportional gain and cut-off frequency of repetitive controller on bearing response speed and stability is discussed
and the controller's design and corresponding parameters tuning method are presented. The experiments are conducted with a high-speed magnetic levitation motor. The experimental results show the validities to suppress the rotor periodic vibration
reduce the third order harmonic components
and improve the control precision of AMB.
