Abstract

It is important to accurately estimate the speed for induction motor speed sensor-less control technology. According to the drawbacks of traditional model reference adaptive system (MRAS), this paper presents an improved estimation model, which can effectively eliminate the DC drift and the initial value problems caused by pure Integrator. On this basis, it analyzes the influence of variable stator resistance on the speed estimation and makes stator resistance online identification to update stator resistance changed by temperature and ensure the accuracy of speed estimation. The simulation and experimental results show the rationality and effectiveness of the method.
