The Variable Frequency Regulation Speed System of Vector Control Without Velocity Sensor

本文介绍的无速度传感器的矢量控制变频调速系统,是应用电压模型计算出电动机转子磁链的实际值,并模拟计算转子的转速,构成磁通定向、具有频率和转矩闭环的矢量控制系统。该系统已投入工业运行。

This paper describes a variable frequency regulation speed system of vector control without velocity sensor. Actual rotating flux of induction motor is calculated by the voltage model, And rotating speed is calculated by simulated method. The system consists of the frequency and torque closed loops with a fieldorientated. This system has been put into opertion in the industry.
