<p>The arrangement has a control path for supplying correcting variable to an adjustable input (19) of a proportional-pressure valve (3), and a pressure sensor detects actual pressure at a connection of the valve. A differential unit (5) determines control deviations as difference between estimated pressure and actual pressure. A controller (8) modifies a signal on the control path based on minimization of the control deviations. A multiplicator (6) is designed in such a manner that large control deviations are strongly attenuated than the small control deviations. An independent claim is also included for a method for controlling pressure in an electro-hydraulic pressure controlling arrangement.</p> |
