Stator-flux-oriented vector control of hybrid excited axial field flux-switching machine

Hybrid excited axial field flux-switching machine (HEAFFSM) is a novel hybrid excited flux-switching permanent magnet machine, which combines the advantages of the hybrid excited synchronous machine and axial field flux-switching permanent magnet machine. Based on the vector control method, a novel control strategy of stator-flux orientation for the HEAFFSM, which can operate in both flux-enhancing and flux-weakening modes, is proposed. The operating performance of the HEAFFSM is investigated in the entire operation region according to the proposed strategy. The simulation and experimental results show that the proposed method is simple and convenient to control, and extends the constant power operating range. Moreover, the characteristics of the HEAFFSM, including the load capability and flux-regulation capability, are validated.
