说明：  为实现电压-频率协调控制，且对调速范围和起制动性能有一定的要求，可以采取转差频率控制进行变频调速。本文采用转差频率控制对异步电机进行变压变频的控制，针对基于转差频率的矢量控制，设计出一种控制模型，并利用MATLAB仿真软件进行了分析。结果表明，转差频率的矢量控制方式具有较好的调速性能，其具备较高的实用价值。
(In order to realize the voltage and frequency coordinated control, and to have certain requirements on the speed range and braking performance, we can adopt the slip frequency control for variable frequency speed control.This paper adopts the slip frequency control to control the variable voltage and frequency conversion of the asynchronous motor. Aiming at the vector control based on the slip frequency, a control model is designed and analyzed with MATLAB simulation software.The results show that the vector control method of the slip frequency has better speed control performance and has higher practical value.)
