N2 - Hybrid excited flux-switching machine (HEFS) is a novel brushless synchronous motor. Compared to conventional permanent magnet synchronous machine (PMSM) and permanent magnet flux switching (PMFS) machine, it has additional excitation winding in its stator to modulate the air-gap magnet field. In this paper, the topology and operating principle of HEFS is analyzed. Its dynamic mathematical models are obtained based on the dq-axis synchronous rotating coordinate system. A novel control strategy for the HEFS control system is proposed in both constant torque range and constant power range. In the constant torque range, the optimized positive excitation current and corresponding q-axis current dealing with the load torque can minimize the total copper loss and achieve rapid response. In the constant power range, the negative excitation current and d-axis current are used to achieve higher speed and broaden the constant power range. The effectiveness of the proposed control strategy for the HEFS control system is confirmed by simulation and experiment.
