Abstract
When employing synthetically commutated hydraulic pumps (), a time delay between a change in fluid flow demand () and the resulting fluid flow output () can be observed. It is suggested to use a time evolvement function, taking into account the time evolvement of the fluid flow demand and/or the time evolvement of the pumping strokes, to modify the actuation of the electrically commutated valves.
