中文摘要：

在深入分析磁悬浮开关磁阻电机（BSRM）径向力模型的基础上，针对BSRM径向位置两自由度上的相互耦合情况，采用反馈线性化方法进行了动态解耦，设计了解耦算法，并对解耦后的线性子系统进行了闭环设计。在Matlab7，0／Simulink环境下进行了整个径向位置控制系统的仿真建模。仿真结果显示，反馈线性化解耦可保证BSRM在径向两自由度上实现独立控制，且闭环系统具有良好的动、静态性能。

英文摘要：

An improved radial force model of bearingless switched reluctance motor （BSRM） considering the affection of radial displacement was proposed. A feedback linearization- based dynamic decoupling algorithm was designed for radial position coupling on two degrees of freedom of BSRM. The two decoupled linear subsystems were synthesized. A Matlab7.0/ Simulink-based simulation was done. The simulation results show that independent control on two degrees of freedom of radial position of BSRM can be realized through feedback linearization decoupling method and the dynamic and static performance of the closed loop system designed is satisfactory.
