摘　　要：提出了一种新型双三相槽口永磁型混合励磁双凸极发电机,建立了该电机的矢量空间解耦数学模型,分析了不同工况下电机的电感特性,并提出了一种考虑电感变化的发电稳压铜耗监督控制策略。该策略建立了以最小铜耗为目标,以转矩、电流和电压为约束的非线性规划模型。首先,查找电感响应面,获得电机在当前工况下的实时电感参数;其次,将实时电感代入模型作二次优化,得到适用于电机当前工况的d轴、q轴优化电流及励磁优化电流,在实现系统稳压发电的同时有效减少铜耗;最后,通过Ansys和Simulink的联合仿真,验证所提控制策略的正确性和有效性。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.
