Abstract
Système de commande à cabestan pour dérouleur à bande. Il comprend un unique cabestan continuellement en contact avec une longueur de bande pour assurer un mouvement bidirectionnel dans tous les modes de fonctionnement. Un moteur à courant continu est directement couplé au cabestan et est excité en vue d'une commande précise du mouvement. Un système d'asservissement hybride est commuté entre une commande numérique de vitesse avec accrochage de phase de position et une commande analogique d'accélération uniforme, pour une commande précise de la vitesse de reproduction et une accélération rapide pratiquement instantanée. Application: commande des dérouleurs de bande acoustique professionnels.
