摘要：
The flux-intensifying interior permanent magnet (FI-IPM) motors feature the negative saliency, wide speed regulation range, strong overload ability and etc. have a wide potential application prospect in the fields of wide speed regulation and multi-operation conditions. This paper focued on the utilization of the negative saliency and wide speed range characteristics, and a multi-running area current segment control strategy was proposed for the motors. The whole operating range of the FI-IPM motor was divided into four parts, namely flux-enhance I, flux-enhance II, flux-weakening I and flux-weakening II. Based on the current coordinated control, the effective control of the motor in the multiple operating areas was realized, and the current mutation and the system instability caused by the positive to negative process of the d axis current were solved. Moreover, the optimal current trajectory could be obtained for the FI-IPM motor which could enhance the load capacity and the stability of the control system. Finally, experimental studies were carried out, and the results verified the effectiveness and stability of the strategy. © 2021 Chin. Soc. for Elec. Eng.
