Abstract

Titre : Transmission hydrostatique, machine mobile équipée d’une telle transmission et procédé de commande de la transmission Transmission de roulage hydrostatique comprenant une première machine hydraulique (2) couplée à une machine d’entraînement et reliée par un circuit hydraulique fermé à une seconde machine hydraulique (4) couplée à une sortie et une unité de commande (12) comportant un modèle de couple (M) de la seconde machine hydraulique (4) ou de la sortie en fonction d’une demande d’accélération (acons), d’un débit réglable (VP), d’au moins l’une (2) des machines hydrauliques (2, 4) ainsi qu’une charge extérieure appliquée à la transmission de roulage (1) ou à la machine de travail. L’unité de commande (12) commande l’installation de réglage (8) des machines hydrauliques en fonction de la valeur de sortie du modèle. La transmission comprend un observateur d’état (26) par lequel on détermine une valeur évaluée de la charge extérieure et on l’introduit au moins comme composante dans le modèle. Figure 1
