改进型感应电机电压模型磁链观测器设计
Improved voltage model flux observer design of induction machine
摘要
Abstract
To address the problems of amplitude and phase error and the best cut off frequency determination when the low-pass filter is introduced into the traditional voltage model flux observer, this paper propose an improved voltage model rotor flux estimation which series high-pass filter and low-pass filter, and integral the voltage factor, as well as the current factor in the voltage model separately, in this paper, we analyzed the reason why this modified voltage model can improve accuracy and performance,derive the compensation algorithm due to the introduction of the amplitude and phase error with the high-pass filter and low-pass filter. Simulation and experimental verified the correction of the compensation algorithm, this modified rotor flux observer has a good dynamic and steady state performance over the motor entire speed range, which also has high value in the engineering practice.关键词
