Cooperative Control Strategy Based on MTPA for A Partitioned Stator DC-Biased Hybrid Excited Permanent Magnet Machine

This paper proposes a partitioned stator DC-biased hybrid excited permanent magnet machine and a cooperative control strategy based on maximum torque per ampere (MTPA) is established and verified. Firstly, the working principle of the proposed machine is introduced, and the dual three-phase configuration of the motor drive is presented. The model of the DC-biased hybrid excited machine based on dual three-phase configuration is established, and the cooperative control method based on maximum torque per ampere is derived. Various simulation and comparison studies of the proposed machine based on the cooperative control are conducted, and the results verify the control performance
