Semiactive and active piezoelectric vibration controls for switched reluctance machine / Mininger, X. in IEEE transactions on energy conversion, Vol. 23 N°1 (Mars 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 N°1 (Mars 2008) . - pp. 78 - 85 Titre : Semiactive and active piezoelectric vibration controls for switched reluctance machine Type de document : texte imprimé Auteurs : Mininger, X., Auteur ; Lefeuvre, E., Auteur ; Gabsi, M., Auteur Année de publication : 2008 Article en page(s) : pp. 78 - 85 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Damping;  machine  control;  noise  abatement;  piezoelectric  devices;  reluctance  machines;  vibration  control Résumé : This paper presents two vibration control approaches using piezoelectric inserts applied to a switched reluctance machine (SRM) in order to reduce acoustic emission. The semiactive approach, called synchronized switch damping, consists of a particular voltage processing that increases the electromechanical energy conversion of the piezoelectric insert and leads to effective vibration energy dissipation. Piezoelectric inserts can also be considered as actuators: the active technique aims at imposing an adequate force in order to compensate the structure strain originated by the electromagnetic forces. These two techniques are compared on a single-phase structure mechanically similar to that of an SRM. Advantages and drawbacks depending on the chosen technique are then discussed.
