Title (EN) SPEED CONTROL SYSTEM
(FR) SYSTEME DE REGULATION DE VITESSE
Abstract:
(EN) A servo control system is separately equiped with an integrator which feeds back the speed of a servo motor and an integrator which feeds back the speed of a mechanical load. The speed of the servo motor and the speed of the mechanical load driven by the servo motor are reflected simultaneously and at a predetermined ratio on a transfer function of the servo control system, in order to realize a pertinent servo control for the mechanical load having small rigidity and to realize a speed control maintaining excellent response and stability.
(FR) Un système de servo-commande est pourvu séparément d'un intégrateur qui réinjecte la vitesse d'un servo-moteur et d'un intégrateur qui réinjecte la vitesse d'une charge mécanique. La vitesse du servo-moteur et la vitesse de la charge mécanique entraînée par le servo-moteur sont réfléchies simultanément et dans un rapport prédéterminé sur une fonction de transfert du système de servo-commande, afin de réaliser une servo-commande adaptée à la charge mécanique possédant une faible rigidité et pour réaliser un système de régulation de vitesse présentant d'excellentes caractéristiques de réaction et de stabilité.
