Abstract
(EN)
This synchronization control device (10) is provided with: a main shaft command calculation unit (Cmm) that calculates a main shaft command position on the basis of chronological target position information; a main shaft model unit (Mm) that uses a predicted main shaft command position after a predetermined length of time calculated on the basis of the main shaft command position, a main shaft feedback position, and the target position information as input to calculate a predicted main shaft feedback position by means of a dynamic characteristic model from a main shaft servo control mechanism (20); and a driven shaft command calculation unit (Cms) that calculates a driven shaft command position on the basis of the predicted main shaft feedback position. As a result of this configuration, it is possible to achieve synchronization control in which the precision of synchronous driving of a driven shaft is improved.

Le dispositif de commande de synchronisation (10) selon l'invention comprend : une unité de calcul de commande d'arbre principal (Cmm), qui calcule une position de commande d'arbre principal sur la base d'informations chronologiques de position cible ; une unité de modèle d'arbre principal (Mm), qui utilise une position de commande d'arbre principal prédite après une durée prédéfinie calculée sur la base de la position de commande d'arbre principal, une position de rétroaction d'arbre principal et les informations de position cible en tant qu'entrée pour calculer une position de rétroaction d'arbre principal prédite au moyen d'un modèle à caractéristiques dynamiques provenant d'un mécanisme de servocommande d'arbre principal (20) ; et une unité de calcul de commande d'arbre entraîné (Cms), qui calcule une position de commande d'arbre entraîné sur la base de la position de rétroaction d'arbre principal prédite. Cette configuration permet d'obtenir une commande de synchronisation dans laquelle la précision d'entraînement synchrone d'un arbre entraîné est améliorée.
