Abstract:A new type of double three-phase slot PMs hybrid excitation doubly salient generator is proposed，and its vector space decoupling mathematical model is established. The inductance characteristics of the motor under different working conditions are analyzed，and a copper loss supervisory control strategy for voltage stabilization considering inductance variation is proposed. The strategy establishes a nonlinear programming model with the minimum copper loss as the objective and the torque，current and voltage as the constraints. Firstly，the real-time inductance parameters of the motor under the current working condition are obtained by searching the inductance response surface. Then the real-time inductance is substituted into the model for secondary optimization and the optimal current of d and q axis and excitation current suitable for the current working condition of the motor are obtained，which can ensure the stable voltage output of the system and effectively reduce the copper loss. Finally，the correctness and effectiveness of the proposed control strategy are verified by the co-simulation of Ansys and Simulink.
