A New Approach Fuzzy-mras-sensorless Vector Control Based Rotor And Stator Resistances Estimation Of An Induction Motor Drive

Authors : S. Chekroun S. .

Abstract

Abstract: This paper introduces a new sensorless vector controlled induction motor based to the parallel resistance parameters and rotor speed estimation for Fuzzy-MRAS Sensorless with Direct Field Oriented Control is discussed in this paper. the analysis of the sensorless vector control system using MRAS is presented and the resistance parameters variations and speed observer using Fuzzy Logic is proposed. The aim of the proposed sensorless control is to improve the performance and robustness of the induction motor drives under non linear loads variations is presented in this work. The availability of the proposed structure scheme is tested in simulation with Matlab-software. The Simulation results will be presented to confirm the theoretical analysis and the efficiency and reliability of the proposed Fuzzy-MRAS sensorless.
