Abstract

In order to solve the problem of strong coupling between torque and suspension force of bearingless switching motor and the strong chattering of sliding mode control, a direct suspension force control method for hybrid stator bearingless switched reluctance motor based on 1uasi-continuous third-order sliding mode is proposed. According to the special structure of hybrid stator bearingless switched reluctance motor, the direct decoupling of torque and suspension force is realized. The suspension force control system adopts the direct suspension force control of the third-order sliding mode. By comparing with the second-order sliding mode control system under the condition of interference source and non-interference source, the results show that the designed control strategy has high precision, strong robustness, fast convergence speed, and it can effectively decrease vibration.
