针对车用电驱动系统的高频噪声问题，研究了永磁同步电机矢量控制系统的转矩波动问题。其主要来源为位置检测产生的影响、电流检测产生的影响、逆变器中产生的误差、磁链谐波以及齿槽效应等电机本体的影响四方面。之后建立永磁同步电机矢量控制MATLAB/Simulink仿真模型，针对角度误差对比分析了转矩波动三维谱图，并与转矩波动分析相验证。最后，给出了两个角度误差引起的转矩波动的抑制方法并通过仿真验证。

According to the high frequency noise problems of automotive electric drive systems, this paper stud-ies the torque ripple problem of permanent magnet synchronous motor vector control system. Its main source is the im-pact of position detection, the impact of current detection, the error generated in inverter and the influence of motor ontology( magnetic chain harmonic and the cogging effect and so on) . Then establish the permanent magnet synchro-nous motor vector control, MATLAB/Simulink simulation model. For the angle error, this paper analyses the torque ripple 3-D spectrogram, verifies the torque ripple analysis. In the end, the two angle fluctuation suppression method was presented, and be verified by simulation.
