Abstract Aiming at the nonlinear coupling problem between the currents and mechanical angular velocity of the hybrid excitation synchronous motor (HESM), the differential geometry theory of nonlinear system was used in this paper, based on the basic current control to achieve the output of low-speed large torque and wide speed regulation range. Through coordinate transformation and state feedback, the exact linearization decoupling conditions and decoupling matrix were deduced. And three linear subsystems that can be independently controlled-the d-axis current subsystem, the excitation current subsystem and the mechanical angular velocity subsystem were obtained. The dynamic decoupling control of the current loop in the global range of the HESM speed regulation system is realized. Through the comparison among exact linearization, partial linearization and traditional control simulation, the results show that the proposed control strategy has good speed tracking ability and strong robustness, and the dynamic and static performance of the system are improved.
