Title:Flatness-Based Control of a Closed-Circuit Hydraulic PressAuthor(s):Helmut Kogler, Karl Ladner, Peter LadnerAbstract:Hydraulic drive technology is well known for its high force density and, hence, basically qualified for press applications. While systems with constant pressure supply suffer from a bad energy efficiency due to resistance control and, furthermore, an inferior controllability in particular at fast movement operation, the presented hydraulic press concept overcomes these drawbacks by using a synchronized cylinder in a closed circuit displacement control for rapid movement and in press mode. In this paper, a flatness-based control of the position of the main press actuator is presented. The derivation of the controller design is followed by simulation experiments and, furthermore, by a discussion of measurements on a two-axis prototype with a load capacity of 50 tons.Booktitle:Dynamics and Control of Advanced Structures and MachinesPublisher:Springer, ChamISBN:978-3-030-79324-1Page Reference:page 111-121, 10 page(s)Publishing:2022Volume:156
