Abstract[German]
Die Erfindung betrifft ein Hydrauliksystem (100), aufweisend: - einen hydraulischen Verbraucher (10); - eine Regelpumpe (30); - ein Regelventil (36); und - einen Systemregler (40) zur dynamischen Positionsregelung des hydraulischen Verbrauchers (10), der Systemregler (40) aufweisend einen Pumpenregler (42) zum Regeln der Regelpumpe (30) und einen Ventilregler (44) zum Regeln des Regelventils (36); wobei der Ventilregler (44) eingerichtet ist, das Regelventil (36) auf Basis einer Soll-Position (46) des hydraulischen Verbrauchers (10), auf Basis eines Abgleiches (48) der Soll-Position (46) mit einer Ist-Position (28) des hydraulischen Verbrauchers (10) und auf Basis eines Verstärkungsfaktors (50) der Regelpumpe (30) in Abhängigkeit von einem Grenzwert zu regeln.[English]
The invention relates to a hydraulic system (100) comprising: - a hydraulic consumer (10); - a control pump (30); - a control valve (36); and - a system controller (40) for dynamically controlling the position of the hydraulic consumer (10), the system controller (40) having a pump controller (42) for controlling the control pump (30) and a valve controller (44) for controlling the control valve (36); wherein the valve controller (44) is designed to control the control valve (36) on the basis of a target position (46) of the hydraulic consumer (10), on the basis of a comparison (48) of the target position (46) with an actual position (28) of the hydraulic consumer (10) and on the basis of an amplification factor (50) of the control pump (30) depending on a limit value.[French]
L'invention concerne un système hydraulique (100) comprenant : - un consommateur hydraulique (10) ; - une pompe de commande (30) ; - une vanne de commande (36) ; et - un dispositif de commande de système (40) pour commander de manière dynamique la position du consommateur hydraulique (10), le dispositif de commande de système (40) ayant un dispositif de commande de pompe (42) pour commander la pompe de commande (30) et un dispositif de commande de vanne (44) pour commander la vanne de commande (36) ; le dispositif de commande de vanne (44) étant conçu pour commander la vanne de commande (36) sur la base d'une position cible (46) du consommateur hydraulique (10), sur la base d'une comparaison (48) de la position cible (46) avec une position réelle (28) du consommateur hydraulique (10) et sur la base d'un facteur d'amplification (50) de la pompe de commande (30) en fonction d'une valeur limite.
