摘　　要：在阐述了无轴承同步磁阻电机(BSRM)工作原理的基础上,建立其数学模型,采用最小二乘支持向量机(LS-SVM)逆系统方法对其进行解耦控制,将原系统解耦成3个相对独立的伪线性子系统,并应用线性系统理论设计了闭环控制器.最后采用Matlab/Simulink构建仿真系统.仿真结果表明:此解耦控制策略能够实现无轴承同步磁阻电机电磁转矩和径向悬浮力之间的动态解耦,且系统具有良好的动、静态特性.The principle of the bearingless synchronous reluctance motor （BSRM） is expatiated and the mathematics model is established. Then the least squares support vector machines （LS-SVM） system method is applied to decoupling control of the BSRM, which decouples the original system into 3 relatively independent SISO pseudo-linear subsystems. At the same time, the closed loop linear controllers are designed based on the linear system theory. The simulation system is constructed with Matlab/Simulink software. The simulation results show that this kind of control strategy can realize dynamic decoupling among electromagnetic torque and radial suspension forces of the BSRM, and the control system has excellent dynamic and static performance.
