Abstract
L'invention concerne un appareil de servocommande destiné à commander la vitesse et a phase d'une pièce entraînée. Des signaux de référence sont comparés avec des signaux représentant la vitesse réelle dans une boucle d'asservissement, de manière que la pièce soit entraînée à la vitesse déterminée par les signaux de référence. Des signaux représentant la position réelle sont également comparés avec des impulsions de fourchette pour que la phase de la pièce entraînée soit réglée dans une plage prédéterminée. L'invention s'applique notamment à l'entraînement des têtes et de la bande magnétique dans un enregistreur d'image de télévision.
