摘要
异步电机矢量控制要求准确获得磁场定向,而磁场定向的精度取决于电机参数值。为了准确辨识出电机的参数,本文研究基于静止状态下异步电机T型等效电路模型,采用脉冲电压法,单相交流注入法取代传统堵转和空载试验,实现对异步电机参数的准确测量。仿真实验结果证明上述方法正确可靠,且得到了较高的辨识精度。
For tha vector control of an induction motor,it require accurately field oriented,while the precision of the field oriented depends on motor parameter values.In order to accurately identify the parameters of the motor,this paper studies on the basic of T equivalent circuit model of induction motor at standstill state,we use pluse voltage or single phase AC as an excitation signals to measure the static of parameter for induction motor,this method don＇t require do locked rotor and no-load tests.The validity,reliability and accuracy of the proposed scheme is verified through simulation.
