| 摘 要： | 介绍了两轴型混合磁悬浮轴承的系统结构,基于分散控制建立了磁轴承的控制系统模型。对磁轴承进行了变结构控制研究,根据二次型最优控制设计了切换函数,根据指数趋近律设计了变结构控制输入,实现了磁轴承的快速稳定和鲁棒性控制。通过与最优控制的对比仿真研究,表明了变结构控制具有良好的动静态特性。

| Abstract: | The configuration of two axial hybrid magnetic bearing was introduced.The control model of dynamic system was founded.The variable structure controller of magnetic bearing was decided.According to the quadratic optimal regulator,the switching function was designed.The input of the control system was calculated by the exponential motion rule.The dynamic response and stability of magnetic bearing were investigated.The simulation shows the variable structure control of magnetic bearing has good performance comparing with the optimal control. |
