A method for controlling a hydraulic system, in particular of a swing expensive algorithm

摘要

A method for controlling a hydraulic system (100), which comprises:– a pump (112) and a tank (114),– an actuating device (116), which has a working chamber,– a valve arrangement (110), is configured for the purpose of the fluid communication between the working chamber and the tank (122, 128) and the fluid communication between the working chamber and the pump (124, 126) to control,– an input device (170), which is operable to selectively the actuating device (116) to control,– a control device (160) in conjunction with the valve assembly (110) and the input device (170), wherein the control device (160) is configured to a flow state and a pressure condition of the working chamber by means of a sensed pressure (150, 152) of the working chamber and a command from the input device (170), by determining a pressure difference, and wherein the pressure difference by subtraction of the sensed pressure of the through the input device (170) predetermined, desired pressure is obtained, characterized in that– the control device..
