A performance based analysis of a robust flux controller for an induction motor drive

Abstract

This paper presents the design of a novel robust flux controller and, subsequently, a robust speed controller for an indirect field oriented controlled induction motor drive. The controllers are obtained in terms of stability and performance criteria, taking into account the effects of external disturbances and parameter variations, including time delay, rotor resistance variances and inertial deviation from the nominal model. The purpose of these controllers is to provide good tracking and performance despite the uncertainties present in the drive system.
