Abstract
UN CIRCUIT DE COMMANDE ENGENDRE UNE TENSION DE SORTIE ANALOGIQUE VARIABLE EN REPONSE A LA FERMETURE FUGITIVE D'UN MOYEN DE COMMANDE SENSIBLE AU TOUCHER PAR UN OPERATEUR. LE NIVEAU DE COMMANDE CHOISI A L'AIDE DU MOYEN DE COMMANDE SENSIBLE AU TOUCHER EST ECHANTILLONNE, NUMERISE, STOCKE NUMERIQUEMENT ET RECONVERTI EN TENSION DE SORTIE ANALOGIQUE POUR COMMANDER UN MOTEUR A UNE VITESSE COMMENSURABLE. LA SELECTION D'UN NIVEAU DE COMMANDE DIFFERENT ENGENDRE UNE VALEUR NUMERIQUE DIFFERENTE DANS UNE MESURE CORRESPONDANTE ET, PAR CONSEQUENT, UNE TENSION DE SORTIE ANALOGIQUE DIFFERENTE. LE NIVEAU DE COMMANDE CHOISI ET LA TENSION DE SORTIE ANALOGIQUE CORRESPONDANTE PEUVENT ETRE MAINTENUS PENDANT UNE PERIODE DE TEMPS PROLONGEE. APPLICATION A LA COMMANDE SUR LE MODE NAVETTE DE DEROULEURS DE BANDE MAGNETIQUE.
