A Novel High-Performance Field-Weakening Control for Axial Flux-Switching Permanent-Magnet Motor
J. Rahmani Fard
Abstract:   (3245 Views)
By combining the field-weakening control principle of a new axial flux-switching permanent-magnet motor (AFFSSPM) with the space vector pulse width modulation (SVPWM) and maximum torque per voltage (MTPV) control principle, a novel field-weakening control strategy for AFFSSPM is proposed in this paper. In the first stage of the field-weakening, the difference between the reference voltage updated by the current regulator and the saturated voltage output with SVPWM is used for field-weakening control, which modifies the direct axis of stator current. This method makes full use of the DC bus voltage, and can naturally smooth transition. In the second stage of the field weakening, the principle of MTPV control is used for field-weakening control, and then, being linearized. Compared with the traditional method, this method solves the problem of depth weakening of AFFSSPM. Between the two stages, the turning speed is used for the switch condition to achieve a smooth transition. The effectiveness and correctness of the proposed field-weakening control method and calculation method were verified with simulation results. Moreover, the dSPACE semi-physical simulation experimental platform for the hardware design and software design is used, and the semi-physical simulation experiment is carried out. The results show the accuracy and effectiveness of the proposed scheme.

  • A new method of field weakening control for the axial flux-switching permanent-magnet motor is proposed.
  • This method can make the motor run in the deep weak magnetic field, so that the motor can run at a higher speed.
  • Linearized the MTPV curve, and simplified the calculation are the specific feature of this method.
  • This control strategy has a very important reference value for the research of the field-weakening control strategy of the permanent magnet synchronous motor drive system.
  • A semi-physical simulation experiment based on dSPACE is done, which effectively verifies the correctness of the proposed method.
