摘要
介绍一种双闭环控制变频调速系统．该系统利用电动机定子有功电流来实现电动机的力矩控制，使系统具有较好的静动态性能且控制简单可靠．
This paper presents a double loop controller for VVVF. The system uses effective current of motor stator to control torque, so it can be operated with good dynamic and static character. It has advantages of simple control, high reliability,etc.
