Sliding Mode Flux Observer of Induction Motor

Abstract

This paper deals with the sliding mode theory for direct torque and flux controlled (DTFC) induction motor drive. The aim of this paper is implementation of sliding mode theory for design of robust sensorless control of the drive with DTFC. This contribution describes proposed control and flux observer as well as presents simulation results and experimentalevidence of the laboratory prototype of the drive.
