Abstract
A control arrangement () of a hydraulic system () is provided, said control arrangement () comprising a supply port arrangement having a high pressure port () and a low pressure port (), a working port arrangement having two working ports (), a first valve () arranged between said high pressure port () and said working port arrangement (), a second valve () arranged between said low pressure port () and said working port arrangement (). Such a control arrangement should enhance the control of a hydraulic system. To this end a controller () is provided for controlling said first valve () and said second valve (), said controller () has an input connection () for receiving a signal of an operator input device and on the basis of said signal said controller at least initially calculates an unbalance between a first flow demand for said first valve () and a second flow demand for said second valve (), and adjusts said first valve () according to said first flow demand and said second valve () according to said second flow demand.
