摘　　要：为提高车用内置式永磁同步电机的调速范围,实现高速巡航能力,论文深入研究了内置式永磁同步电机带励磁电流补偿的弱磁控制新策略。首先,分析了带励磁电流补偿的弱磁控制原理,其次,在Matlab/Simulink仿真平台上搭建了系统仿真模型。最后,对控制系统进行了仿真,仿真结果表明,所研究的控制策略能够实现恒转矩区至恒功率区的平滑过渡,动态响应快,并提升弱磁升速能力,为提升车用内置式永磁同步电机的应用具有一定的借鉴意义。In order to improve the vehicle speed range and high speed cruise capability of the interior permanent magnet synchronous motor,the flux weakening control strategy with excitation current compensation is studied in this article. The interior permanent magnet synchronous motor field weakening control system simulation model is established based on the platform of MATLAB / Simulink,and high speed weak magnetic control system simulation is carried out.The simulation results show that the system has a wide range of speed regulation and fast dynamic response,and the method provides a reference significance for further study on the highspeed cruise and overtaking and other conditions.
