Abstract :
The aim of this paper is to present a solution to the problem of induction machines rotor flux reconstruction and rotor resistance estimation by using a sliding mode observer based on singular perturbation theory. This approach allows the decomposition of the original model, described in two-time-scales, into two reduced-order models. Based on simulations, this study shows an acceptable behaviour of the combined indirect field oriented control (IFOC) and the observer even with the variation of parameters such as rotor resistance.
