COMMANDE DE LA MACHINE ASYNCHRONE PAR ORIENTATION DU FLUX ROTORIQUE

Dans cet article, nous proposons la commande de la machine asynchrone avec orientation du flux rotorique. Cette commande consiste à éliminer le problème de couplage entre l’induit et l’inducteur en dissociant le courant statorique en deux composantes, en quadrature dans un repère de référence lié au champ tournant, de telle sorte que, l’une des composantes commande le flux tandis que l'autre commande le couple. Les résultats de l'étude, exprimés en régime de démarrage et en régime de charge, sont largement présentés et discuter

ABSTRACT Brucellosis is a debilitative disease that imposes costs on both economy and society. It is shown that although the vaccine can prevent abortion, it does not provide complete protection against infection. In Iran, Brucella melitensis is a common causative agent for brucellosis and BP26 protein of this bacterium having a good antigenesity and an important vaccine candidate. In this study B. melitensis bp26 gene was cloned first in to PTZ57R/T vector and accessed on the PET28a vector and sequenced. Recombinant vector transformed and expressed in to E. coli BL21 (DE3) and then recombinant protein was purified with Ni-NTA column of chromatography against His tag. Obtained rOmp28 could be used as a research experimental tool to find its potential as a detection kit and vaccine candidate
