摘要
介绍一种简易的异步电机参数辨识方法,该方法能在电机静止状态下辨识出电机的各个参数,并在基于TMS320F2812为主控制器的异步电机无速度传感器矢量控制系统进行实验,将辨识得到的参数投入到实际系统中,通过LabVIEW虚拟示波器观测系统的实际运行情况。实验结果证明该方法辨识得到的参数准确性高,能直接应用于无速度矢量控制系统,而避免了繁琐的参数整定过程。
Presented a simple induction motor parameter identification method.This method can identify the parameters of the induction motor in a stationary state.Experiment was carried out on speed sensorless vector control system based on TMS320F2812.Parameters obtained from the identification were input to the vector control system.LabVIEW virtual oscilloscope was used to observe the operation conditions of the system.The experimental results show that this method can identify the parameters with high accuracy.This method can be applied to speed sensorless vector control system,avoiding the cockamamie process of parameter tuning.
