基于自抗扰控制技术的感应电动机MRAS转速估计研究
Study on MRAS speed estimator of induction motor based on active disturbance rejection control technique
摘要
Abstract
This paper proposes a novel model of stator - current - based MRAS speed estimator for induction motor. The estimator uses induction motor as reference system and stator current as state - variable of the reference system which can be measured directly. The stator voltage - current equation is used as adjustable model. A speed adaption law is proposed based on Popov' s criterion and used to calculate the speed. The rotor flux is observed through an expended - state - observer without the information of rotor speed. The proposed rotor flux observer is also independent with the rotor resistance, and has robust performance in practical application. Simulation is carried out using Matlab, and the result illustrates the effectiveness of speed estimator.关键词
