Abstract

This paper presents a technique of adaptation mechanism based on a fuzzy controller for speed estimation using model reference adaptive system (MRAS) approach in a direct filed oriented control. The estimated speed is used as feedback for control system. The aim of this mechanism is to improve the control and sensorless speed estimation of induction motor in high, low speed and also under a load torque vibrations. The major contributions of this mechanism are verified by simulation under Matlab/Simulink. Simulation results are presented in order to prove the performance of this mechanism.
