Abstract

Ensemble de commande asservie numérique. Les signaux de référence de plusieurs résolveurs sont fournis par un compteur cyclique 64, une mémoire morte 65 et deux convertisseurs N/A 66 et 67. L'état du compteur 65 est échantillonné cycliquement d'après la phase du signal de sortie des résolveurs pour fournir un groupe de signaux numériques de position effective qui sont comparés à des signaux numériques de position de consigne fournis par un lecteur de bande 106 associé à un interpolateur 114 pour former un groupe de signaux d'erreur de vitesse analogiques attaquant des circuits d'asservissement gérés par un contrôleur 118. L'invention s'applique notamment à la commande numérique des machines-outils.
