Abstract:
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.
