Induction Motor Flux Estimation using Nonlinear Sliding Observers

Hakiki Khalid, Mazari Benyounès and Djaber Sid’Ahmed

Abstract

A nonlinear sliding flux was proposed for an induction motor. Its dynamic observation errors converge asymptotically to zero, independently from the inputs. The aim of this work was to study the robustness of this observer with respect to the variation of the rotor resistance known to be a crucial parameter for the control. The dynamic performance of this sliding observer was compared to that of Verghese observer via a simulation of an IM driven by U/F control in open loop.
