To enhance the robustness of rotor radial magnetic suspension, a rotor magnetic suspension control strategy for a bearingless flux-switching permanent magnet motor (BFSPMM) is proposed, which is based on the combination of the nonlinear feedback linearization theory and internal model control method. Under this control strategy, the rotor dynamic model of the BFSPMM is taken as the internal model, the difference between the actual motor and the internal model output is expanded into a novel nonlinear error system by a second-order filter, and the given suspension current is calculated according to the input-output feedback linearization theory. Simulation and experimental results show that the proposed control strategy can effectively realize the high robust operation control of rotor radial magnetic suspension.
