ABSTRACT
Aiming at the speed identification problem of induction motor without speed sensor vector control, a mathematical model based on asynchronous motor d-p axis is designed. Firstly, the position sensorless control system of asynchronous motor based on model reference adaptive method (MRAS) is established. Then, the estimation error of position sensorless control system is analyzed, the feasibility of the system is proved. Simulation and experimental researching on the dynamic performance of the system show that the system has small speed fluctuation, accurate speed estimation, good system robustness and good dynamic and static characteristics.
