Abstract

For a hydraulic press controlled by the rotational speed of the pump, a positioning controller is developed. The controller has to meet various requirements concerning accuracy, robustness, and rise time. This results in a state controller adapting to position in a pressure-dependent way. Controller performance is investigated by simulation and experiments. The influence of pump pulsations is shown to be very small, whereas the implementation of a motor speed feedback makes a big difference.
