摘 要:在速度分区控制的基础上提出一种混合励磁电机矢量控制算法,该方法综合考虑了负载转矩、励磁电流及母线电压对弱磁基速的影响,在线动态计算弱磁基速。在弱磁区,保持气隙合成反电势恒定,利用励磁电流和d 轴电流共同弱磁升速。采用Matlab/Simulink仿真软件建立混合励磁同步电机控制系统,对所提算法进行验证。仿真结果表明该算法可实现混合励磁电机低速大转矩和高速宽调速范围运行。

Abstract: Based on speed stage control, this paper proposed a kind of vector control algorithm for hybrid excitation synchronous machine (HESM). In this method, load torque, excitation current and DC bus voltage were considered when the fux-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 fux-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.
          Key words: hybrid excitation synchronous motor; stage control; flux-weakening base speed; synthesis back-electromotive force
