摘　　要：针对电动汽车电机运行工况的不同,分析了电动汽车用内置式永磁同步电机矢量控制策略。对内置式永磁同步电机采取最大转矩/电流控制和基于电压反馈补偿去磁电流的弱磁控制策略,运用了SVPWM技术建立电机控制系统。以启辰晨风2014款领风版电动汽车作为研究对象的载体,并以ACR、ASR的双闭环控制进行仿真分析,说明该控制系统应用于电动汽车驱动系统,具有转矩脉动小,静态与动态响应特性好的优点。Aiming at the different operating conditions of electric vehicle motor,the vector control strategy of Permanent Magnet Synchronous Motor（PMSM） for electric vehicle is analyzed. The maximum torque/current control and the flux-weakening control strategy based on voltage feedback compensation are used in the built-in permanent-magnet synchronous motor. SVPWM is used to establish the motor control system. The simulation results of ACR and ASR double closed-loop control show that the control system is applied to the electric vehicle drive system,and has the advantages of small torque ripple,static state and low torque ripple. Dynamic response characteristics of good advantages.
