Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 23 n°2 (Juin 2008) . - pp. 412 - 422 Titre : Robust adaptive control of linear induction motors with unknown end-effect and secondary resistance Type de document : texte imprimé Auteurs : Kuang-Yow Lian, Auteur ; Cheng-Yao Hung, Auteur ; Chian-Song Chiu, Auteur Année de publication : 2008 Article en page(s) : pp. 412 - 422 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Adaptive control  control system synthesis  linear induction motors  machine position robust velocity Résumé : This paper proposes a novel robust adaptive speed/ position tracking control for a linear induction motor (LIM) with both end-effect and secondary resistance unknown. The practical current-fed controlled LIM, with residual current error, is considered, i.e., the traditional ideal current-loop assumption is relaxed. More practical conditions, such as bounded primary voltage and a finite absolute-integral of current tracking error is considered. To overcome the high nonlinearity and nonzero current error, a backstepping method, combining virtual desired variable synthesis, is developed for the speed and position tracking. Then, the controller achieves asymptotic speed and position tracking even with unknown parameters and immeasurable secondary flux. Furthermore, the effect of the residual current error is attenuated in an L2 -gain sense. The experiments for several scenarios are carried out to verify the theoretical result.
