Research of Control Methods for Axial Field Flux-Switching Permanent Magnet Machine

A new type of 6/13-pole axial field flux-switching permanent magnet (AFFSPM) machine is proposed in this paper, which has the advantages of compact structure, large torque density, high efficiency and good fault tolerance. The topology structure of AFFSPM machine is analyzed and the mathematical model is derived in this paper, and then on basis of which, the vector control, direct torque control and model predictive torque control methods are applied for the drive system of the AFFSPM machine and studied by MATLAB/Simulink. The static and dynamic characteristics are compared and analyzed under the three control methods. The simulation results show that the model predictive torque control can make the control system of the AFFSPM machine get better static and dynamic operation performance.
