摘　　要：为了实现新型混合励磁电机的高速运行,文章提出了一种便于实现的基于相电压反馈的弱磁控制策略。通过电机相电压反馈值和逆变器最大输出电压之间的差值来判断电机弱磁区域的边界。控制算法将电机运行区域分为低速、高速I区和II区3个区域,并给出了在高速区d轴电流、q轴电流和直流励磁电流的具体控制方法,通过对混合励磁电机电枢电流和直流励磁电流的共同调节,实现了混合励磁电机在高转速区域的稳定运行。仿真和实验结果验证了该方法的有效性。A Flux weakening control strategy by using feedback phase voltage for the novel hybrid excited permanent magnet machine was proposed in this paper. The error between the feedback voltage and the maximum output voltage of inverter was used to determine the operation region of flux weakening control. In the control strategy, the operation regions is divided into low speed region, high speed region I and II. In the high speed region, the d -axis flux linkage can be controlled by the DC field current and the d-axis current. The control strategy of armature currents and DC field current in the high speed region was presented in the paper to realize stable operation. The proposed method was verified by simulation and experimental results.
