Abstract

L'invention concerne les asservissements de régulation de vitesse. Le dispositif de l'invention comporte un soustracteur algébrique 36 qui reçoit un signal de vitesse réelle provenant d'un capteur 29 par l'intermédiaire d'un circuit de mise en forme 34, et un signal de référence de temps qui est défini par un générateur interne 35. Le signal de sortie numérique du sous-tracteur 36 est appliqué à un convertisseur numérique-analogique 39 pour donner une tension d'erreur analogique 28 qui commande la vitesse du moteur 21. Application à la régulation de la vitesse des moteurs à explosions.
