Method for controlling the movement of a boom, and work machine

A work machine, comprising:

• a boom;
• a plurality of hydraulic drives which are configured to move the boom, a respective hydraulic drive being fed with a hydraulic medium, the pressure of which and/or the volumetric flow of which is settable;
• a setting device, by which a desired movement direction and a desired speed of a boom tip is specified,
• a computing unit which is configured to predictively calculate a respective required pressure and/or a respective required volumetric flow for one or more hydraulic drives which are required for the desired movement direction and the desired speed based on measured values of sensors which detect an instantaneous load of the boom and based on a boom model;
• a pressure generating device and/or a volumetric flow generating device configured, following the predictive calculating, to generate a supply pressure in a manner dependent on the predictively calculated pressures and/or a supply volumetric flow in a manner dependent on the predictively calculated volumetric flows;
• and
• a feed device configured to bring about subsequent feeding of the one or more hydraulic drives which are required for the desired movement direction and the desired speed with the hydraulic medium at a respective feed pressure and/or a respective feed volumetric flow such that the boom tip moves in the desired movement direction at the desired speed.
