摘　　要：Although the five-degree-of-freedom magnetic levitation system composed of two conical bearingless switched reluctance motors(CBSRMs)owns the simplest structure,the torque and levitation forces are coupled greatly.Therefore,it is difficult to make the rotor rotate and be fully levitated simultaneously.To solve this problem,two different role division control strategies are proposed in this paper,i.e.individual role division and mutual role division control strategies.The difference between them is the selection of motor which controls the torque or the axial force.In order to understand the characteristics of control variables,the principle and mathematical model of CBSRM are introduced.After that,two control strategies are explained in detail.To verify the demonstrated performance,the simulations are completed with MATLAB/Simulink.由两台锥形无轴承开关磁阻电机可构成结构最为简单的五自由度磁悬浮系统,但其转矩和悬浮力之间存在较大的耦合,因此很难同时实现转子的旋转和五自由度悬浮。针对这一问题,本文提出了两种不同的分工控制策略,即单分工控制策略和双分工控制策略。二者的区别在于主控转矩电机和主控轴向力电机的选择。为了了解控制变量的特性,介绍了锥形无轴承开关磁阻电机的原理和数学模型,然后详细阐述了两种控制方法。最后,利用MATLAB/Simulink仿真验证了所提算法的性能。
