They are dependent on the size of the load, the pressure gain at the valve and [...] the loop gain vK. All these errors are more or less cancelled out if appropriate measures are taken at the position control stage.

Together with a differential cylinder with an annular area pressurised at operating pressure (replacement circuit for hydraulic bridge D), the two edge control enables movement
