MRAS sensorless vector control of an induction motor using new sliding-mode and fuzzy-logic adaptation mechanisms / Gadoue, S.M. in IEEE transactions on energy conversion, Vol. 25 N° 2 (Juin 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25 N° 2 (Juin 2010) . - pp. 394 - 402 Titre : MRAS sensorless vector control of an induction motor using new sliding-mode and fuzzy-logic adaptation mechanisms Type de document : texte imprimé Auteurs : Gadoue, S.M., Auteur ; Giaouris, Damian, Auteur ; Finch, J.W., Auteur Année de publication : 2010 Article en page(s) : pp. 394 - 402 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : fuzzy  control;  induction  motors;  machine  vector  control;  model  reference  adaptive  control  systems;  rotors;  variable  structure  systems Résumé : In this paper, two novel adaptation schemes are proposed to replace the classical PI controller used in model reference adaptive speed-estimation schemes that are based on rotor flux. The first proposed adaptation scheme is based on sliding-mode theory. A new speed-estimation adaptation law is derived using Lyapunov theory to ensure estimation stability, as well as fast error dynamics. The other adaptation mechanism is based on fuzzy-logic strategy. A detailed experimental comparison between the new and conventional schemes is carried out in both open- and closed-loop sensorless modes of operation when a vector control drive is working at very low speed. Superior performance has been obtained using the new sliding-mode and fuzzy-logic adaptation mechanisms in both modes of operations.
