摘　　要：为了减少异步电机输出转矩的波动以及提高直流母线电压的利用率,在深入研究空间矢量脉宽调制(SVPWM)原理的基础上,在Matlab/Simulink软件平台搭建了SVPWM仿真模型,并应用于异步电机的矢量控制系统进行了仿真,仿真结果表明SVPWM控制策略能有效减少转矩波动,提高直流电压利用率。In order to reduce the output torque ripple and improve the utilization of DC voltage in the vector control system of asynchronous motor, an in-depth research on space vector pulse width modulation principle was performed. Based on which, a SVPWM simulation model was built on the Matlab/Simulink platform. And then it was applied to the simulation on vector control system of asynchronous motor. Simulation result indicates that the SVPWM control strategy can reduce torque ripple effectively and improve DC voltage utilization.
