A Novel Scheme of Speed Estimation for Induction Motor Speed Sensorless Vector Control

Zhong-Ling Xu

Abstract

The paper presents a novel scheme for speed sensorless vector control of induction motor.The speed estimator and flux observer are based on dynamic model of induction motor.A simulation model of speed sensorless vector control system is established based on MATLAB/SIMULINK's power system blocksets.At last,the simulation results are shown and it suggests that the model is right by simulating waves and the control system has satisfactory identification precision, excellent dynamic and static performances and high control effect.
