Abstract

SYSTEME DE COMMANDE DE POSITIONNEMENT QUI COMMANDE UN OBJET A UNE POSITION DE CIBLE EN UTILISANT UN SERVO-SYSTEME, CARACTERISE EN CE QUE LA DEVIATION DE POSITION ENTRE LA POSITION ACTUELLE DE L'OBJET A COMMANDER ET LA POSITION DE CIBLE VOULUE EST INFERIEURE A UNE VALEUR PREDETERMINEE. LE SERVOSYSTEME EST ACTIONNE SUIVANT LA DEVIATION DE POSITION AU MOYEN D'UN SIGNAL DE COMMANDE SUPERIEUR A UN SIGNAL DE COMMANDE DONNE PAR GAIN DE RETOUR DE POSITION QUI PEUT ETRE STABLE DANS LE SERVOSYSTEME, ET ENSUITE COMMUTE A UN SERVOSYSTEME ACTIONNE PAR LE GAIN DE RETOUR DE POSITION.
