For traditional permanent magnet synchronous motor (PMSM) flux weakening method, it is easy to cause voltage command saturation and the system lose control. In order to solve this problem, we propose a high speed PMSM anti-saturation regulation method based on hybrid flux weakening technology. The feedforward channel of this method is designed as a two-dimensional table of torque/flux linkage. The expected value of the current current of dq axis is directly checked through the current flux linkage and torque instruction to ensure the dynamic response of the system. In the feedback channel, the voltage instruction compensation link is proposed in this paper. In combination with the output instruction of the current controller, the speed and bus voltage information, the flux instruction required by the feedforward channel is adjusted. Finally, the experimental results verify that the proposed method meets the requirements of high-speed PMSM fast dynamic response, and improves the reliability of the system when it is running at high speed.
