| Abstract: | Aiming at the problem of steady-state and dynamic performance degradation due to flux observer in the vector control of an asynchronous motor.This paper presents a new properties of adaptive control combining with the vector control strategies and designs an adaptive rotor flux observer.Then,comes the induction motor rotor flux observer adaptive algorithm.And the vector control closed-loop system of speed and flux has been constituted by means of the observer.The simulation result indicates that the system has certain robustness,good steady and dy- namic performance. |
