Fault detection and diagnosis in a set “inverter–induction machine” through multidimensional membership function and pattern recognition / Ondel, Olivier in IEEE transactions on energy conversion, Vol. 24 N° 2 (Juin 2009) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 24 N° 2 (Juin 2009) . - pp. 431 - 441 Titre : Fault detection and diagnosis in a set “inverter–induction machine” through multidimensional membership function and pattern recognition Type de document : texte imprimé Auteurs : Ondel, Olivier, Auteur ; Clerc, Guy, Auteur ; Boutleux, Emmanuel, Auteur Année de publication : 2009 Article en page(s) : pp. 431 - 441 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  machines;  electric  drives;  fault  diagnosis;  pattern  recognition Résumé : Nowadays, electrical drives generally associate inverter and induction machine. Thus, these two elements must be taken into account in order to provide a relevant diagnosis of these electrical systems. In this context, the paper presents a diagnosis method based on a multidimensional function and pattern recognition (PR). Traditional formalism of the PR method has been extended with some improvements such as the automatic choice of the feature space dimension or a ldquononexclusiverdquo decision rule based on the k-nearest neighbors. Thus, we introduce a new membership function, which takes into account the number of nearest neighbors as well as the distance from these neighbors with the sample to be classified. This approach is illustrated on a 5.5 kW inverter-fed asynchronous motor, in order to detect supply and motor faults. In this application, diagnostic features are only extracted from electrical measurements. Experimental results prove the efficiency of our diagnosis method.
