Interior Permanent Magnet Synchronous Motor (IPMSM) has the advantages of high efficiency, good performance of speed regulation and so on. So the IPMSM is suited to high-speed train traction system. This paper introduces the operation principle of IPMSM which used in high-speed train traction and the process of flux-weakening control under the limit of the current limit trajectory and the voltage limit trajectory. When the IPMSM’s speed is higher than the rated speed, the q-axes current and d-axes current couple deeply, the traditional flux-weakening control strategy can’t achieve ideal control effect. The paper introduces a flux-weakening control strategy which is easy to achieve and has good robustness—a single current regulator flux-weakening control strategy. The single current regulator flux-weakening control strategy broadens the motor speed range and makes the IPM used in high-speed train operate steady with high speed. The simulation of the traditional flux-weakening control strategy and the single current regulator flux-weakening control strategy in MATLAB/SIMULINK proves that the single current regulator flux-weakening control strategy can easy to achieve and has wide speed range, rapid response speed and good robustness.
