Abstract

A.CIRCUIT DE COMMANDE DE VITESSE D'UN MOTEUR COMPRENANT UN CAPTEUR DONNANT DES IMPULSIONS DONT LA PERIODE VARIABLE EST LIEE A LA VITESSE DU MOTEUR. B.CIRCUIT CARACTERISE PAR UN MOYEN D'ECHANTILLONNAGE COUPLE AU CAPTEUR ET AU GENERATEUR DE SIGNAL D'AMPLITUDE VARIABLE POUR CREER UN SIGNAL DE SORTIE LIE A L'AMPLITUDE MAXIMALE V DU SIGNAL D'AMPLITUDE VARIABLE EN UTILISANT LES IMPULSIONS DU SIGNAL POUR ASSURER QUE L'AMPLITUDE DU SIGNAL VARIABLE DETERMINE LE SIGNAL DE SORTIE SEULEMENT PENDANT LES IMPULSIONS DE SIGNAL.
