| 摘 要： | 径向磁轴承谐振电路的使用使磁轴承不再需要单独的位移传感器.我们通过径向磁轴承的工作原理,运用控制系统理论分析了径向磁轴承的稳定性.分析表明,径向磁轴承谐振电路的方案在动态过程不稳定,但通过仿真研究的结果表明,径向磁轴承谐振电路虽然存在一定稳态误差,但可以通过PD控制器达到悬浮稳态.

| Abstract: | A structure of a radial magnetic bearing with resonance circuit is proposed,which dose not need separate displacement sensors.The operating principle of the radial magnetic bearing is also introduced.The stability of the radial magnetic bearing is analyzed by the control system theory.The analysis shows that the proposed radial magnetic bearing with resonance circuit is instable in dynamic state process.The simulation study on an example shows that the radial magnetic bearing with resonance circuit can levi... |
