MRAS Sensorless Speed Control of an Induction Motor Drive based on Fuzzy Sliding Mode Control

Abstract

This paper is focussed on a MRAS sensorless speed control based on hybrid fuzzy-sliding mode control strategy associated with the field-oriented control of induction motor drives. In order to improve the performance of the speed sensorless vector controlled induction motor drives, an hybrid is included. The analysis, design of the MRAS sensorless control based on fuzzy-sliding mode controller for indirect vector control of induction motor are analyzed and presented. The model is carried out using Matlab/Simulink software. The main advantages of the proposed chattering-free speed controller are robustness to parameter variations and load changes. The results are shown to verify the effectiveness of the proposed speed controller and its advantages are shown in comparison with the conventional SMC and Fuzzy Sliding Mode Controller FSMC.
