Method with a hydraulic pressure medium supply arrangement, and hydraulic pressure medium supply arrangement

Abstract

A method with a hydraulic pressure medium supply arrangement for an open hydraulic circuit having a hydraulic machine, an adjusting mechanism, and an electronic control unit is disclosed. The method includes the steps of reading an actual value and a setpoint value associated therewith for hydraulic operating variables of the hydraulic machine into a first outer control loop and determining the first manipulated variables resulting therefrom. In further steps of the method, the actual values and further setpoint values of the hydraulic operating variables are read into a second outer control loop, compared with one another, and, on the basis thereof, at least one second manipulated variable is determined. Depending on the first and second manipulated variables, a setpoint adjustment speed is then determined as a manipulated variable for the adjusting mechanism. A hydraulic pressure medium supply arrangement which is designed to carry out the above method is also disclosed.
