| 摘 要： | 为了研究异步电机矢量控制系统在不同负载下的动态特性,在利用Matlab/Simulink构建二相静止α-β坐标下异步电机数学模型的基础上,建立了基于电压空间矢量脉宽调制(SVPWM)的异步电机矢量控制模型,并对电机的启动性能以及负载为阶跃、斜坡和正弦输入的情况进行了仿真分析。仿真结果表明所构建的系统模型动态过程符合实际调速系统运动过程。

| Abstract: | Aiming at studying dynamic characteristics of vector control system for asynchronous motor on different load on this basis,a mathematical model of asynchronous motor in static α-β coordinate was established by the Matlab/Simulink,a simulation model of asynchronous motor vector control system based on space vector pulse width modulation（SVPWM） was established.Then some situations such as starting performance and input load for step,ramp and sine wave were simulated and analyzed.The simulation results prove that the above model＇s dynamic process accords with practical speed regulating process. |
