摘　　要：针对内置式永磁同步电机在深度弱磁区域中电流失控的问题,在传统电压调节弱磁控制基础上,提出了基于电压调节的MTPV深度弱磁控制策略,并利用MATLAB/Simulink对该控制策略进行仿真分析。仿真结果表明:与传统电压调节弱磁控制相比,该控制策略在深度弱磁状态下能够避免电流失控,显著提升电机的稳定性。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-weakening 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 results show that compared with the traditional strategy,the proposed control strategy can avoid the current runaway under deep field-weakening conditions and significantly improve the motor's stability.
