摘　　要：SVPWM(Space Vector Pulse Width Modulation)技术应用于交流异步电动机调速系统中不但改善了脉宽调制PWM(Pulse Width Modulation)技术存在的直流电压利用率偏低的缺点而且具有电机转矩脉动小、动态响应快、噪声低等优点。本文以两相静止的αβ坐标系中异步电机的数学模型为基础,运用Matlab/Simulink软件对采用转子磁场定向矢量控制策略的SVPWM控制系统进行了仿真,仿真结果说明文中建立的三相异步电机仿真模型和所用的SVPWM控制算法是正确和有效的。SVPWM technology applied in AC asynchronous motor speed regulation system can not only improve the shortcoming of low DC voltage utilization in the pulse-width modulation technology,but have little motor torque ripple,fast dynamic response and low noise advantages.This paper simulated SVPWM control system with rotor magnetic field directional vector control strategy by Matlab/Simulink,the simulation results prove that the simulation model of three-phase asynchronous motor and SVPWM algorithms used in this paper are correct and effective.
