异步电动机直接矢量控制的MATLAB实现

his paper is based on vector control,analysis the magnetic linkage current model of rotor based on two-phase rotary coordinate system,propose the timing method of two-closed loop and emulate the system based on MATLAB/Simulink and get a real simulink result.According to the flux observer it used the current model and voltage model and give separate MATLAB simulation test which based on different frequence and modulation.It conclude that the voltage model is fit to high speed and the current model is suitable for low speed.Above all,the result of experiment include that the system is good at static and dynamic properties.The system can be formed conveniently with different purposes and has a great practical value.
