In this paper, a model of a bearingless permanent magnet synchronous motor (BPMSM) is proposed, the expressions of radial suspension forces are derived, and an accurate model is established. Furthermore, decoupling and basic linearization are carried out for the radial suspension forces using the theory of differential geometry, and a sliding mode controller with fractional order based on a neural network is designed for the decoupled, pseudo-linear subsystem. Finally, a simulation experiment is conducted for the designed control system and the feasibility of this decoupling control approach is validated. The simulation results indicate that the application of the proposed control scheme to a bearingless permanent magnet synchronous motor modeled using differential geometry can achieve steady and independent control of radial suspension forces.
