这是一个运用矢量控制方法实现异步电机调速的matlab模型，可以输出理想波形，绝对正确。-This is an asynchronous motor speed regulation using vector control method of matlab model, can output the ideal waveform, absolutely right.

本文建立了一个基于直接转矩控制的异步电机变频调速系统。系统采用了两个滞环控制器,分别比较定子给定磁链与实际磁链、给定转矩与实际转矩的差值,然后根据这两个差值查询逆变器电压矢量开关表得到施加在异步电动机定子绕组上的电压矢量,然后通过脉冲宽度调制(Pulse Width Modulation,PWM)逆变器控制异步电动机。(An asynchronous motor variable frequency speed regulation system based on direct torque c
