Abstract

Système de commande intégré à boucle fermée pour moteur à combustion interne dans lequel les fonctions de fourniture de combustible et de cadencement sont fermées autour de la mesure de la vitesse instantanée de rotation du vilebrequin du moteur. Système dans lequel des signaux indicatifs du profil de chaque impulsion de couple communiquée au vilebrequin par la combustion du mélange air-combustible sont engendrés et analysés pour détecter des perturbations causées par des écarts d'au moins deux paramètres de fonctionnement du moteur depuis des valeurs désirées; et des signaux de correction indicatifs de l'amplitude des perturbations détectées sont engendrés pour corriger les fonctions de fourniture de combustible et de cadencement d'un moyen de commande du moteur afin de réduire les différences entre les valeurs réelles des paramètres de fonctionnement et les valeurs désirées, ces signaux de correction pouvant être appliqués au moyen de commande par une matrice de variables d'état intégrant la commande d'au moins un paramètre en fonction d'au moins deux signaux de correction différents.Integrated closed-loop control system for internal combustion engine in which the functions of fuel delivery and timing are closed around the measurement of the instantaneous rotational speed of the engine crankshaft. A system in which signals indicative of the profile of each torque pulse imparted to the crankshaft by the combustion of the air-fuel mixture are generated and analyzed to detect disturbances caused by deviations of at least two engine operating parameters from desired values ; and correction signals indicative of the magnitude of the disturbances detected are generated to correct the fuel delivery and timing functions of an engine control means to reduce the differences between the actual values of the operating parameters and the values. desired, these correction signals being able to be applied to the control means by a matrix of state variables integrating the control of at least one parameter as a function of at least two different correction signals.
