Research ArticleOpen accessIn the author namesInduction Motor Flux Estimation using Nonlinear Sliding ObserversHakiki Khalid, Mazari Benyounès, Djaber Sid’AhmedA 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 … …Journal of Mathematics and Statistics, Vol. 3, Issue 2 · 30 Jun 2007 · 6,794 accessesView PDFCite
Research ArticleOpen accessIn the author namesFault Reconstruction Using Sliding Mode ObserversK. Hakiki, B. Mazari, A. Liazid, S. DjaberIn this study, a nonlinear sliding observer is proposed to explicitly reconstruct fault signals. The novelty lies in the application of the equivalent output injection concept. Previous work in the area of fault detection has used disruption of the sliding motion to detect faults. The aim of the present study was to design a robust observer that slides in the … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 6,680 accessesView PDFCite
