永磁同步电机深度弱磁失控分析及其应对策略研究OA

To address the issue of current runaway of interior permanent magnet synchronous motors(IPMSMs)in deep field-weakening regions,building upon traditional voltage-regulated field-weaken-ing control,a maximum torque-per-voltage field-weakening control strategy was proposed based on voltage regulation,and simulation analysis was conducted with MATLAB/Simulink.The simulation re-sults show that compared with the traditional strategy,the proposed control strategy can avoid the cur-rent runaway under deep field-weakening conditions and significantly improve the motor's stability.
