Piezoelectric actuator design and placement for switched reluctance motors active damping / Ojeda, X. 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. 305 - 313 Titre : Piezoelectric actuator design and placement for switched reluctance motors active damping Type de document : texte imprimé Auteurs : Ojeda, X., Auteur ; Mininger, X., Auteur ; Hamid Ben Ahmed, Auteur Année de publication : 2009 Article en page(s) : pp. 305 - 313 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Active  filters;  damping;  finite  element  analysis;  genetic  algorithms;  minimisation;  piezoelectric  actuators;  reluctance  motors;  stators;  vibrations Résumé : This paper describes the design and the placement of piezoelectric actuators on switched reluctance motors by means of a genetic algorithm (nondominated sorting genetic algorithm II) for the purpose of reducing stator vibrations. Two distinct approaches are presented: one energy-related and the other based on a minimization of the resultant displacement. These methods lead to design and placement strategy for the piezoelectric actuators. A number of optimal actuators obtained using these kinds of approaches is also compared with mechanical finite-element simulations. At last, a solution is achieved in order to validate optimal placement using positive position feedback active filtering.
