Abstract

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.
