Based on speed stage control, this paper proposed a kind of vector control algorithm for hybrid excitation synchronous ma-chine (HESM). In this method, load torque, excitation current and DC bus voltage were considered when the flux-weakening base speed was calculated. The air gap synthesis back-electromotive force was kept constant in high-speed region applying excitation and d-axis current for flux-weakening. Simulink in Matlab was adopted to build the HESM control system and the algorithm was validated. The simulation results show that this new control system has higher output torque and broader constant power operation scope.
