Electrohydraulic control device and adjustable hydraulic pump system

An electrohydraulic control device for an adjustable hydraulic pump system, comprising:

• a valve device;
• an electronic control unit;
• and
• at least one first fluid sensor,
• wherein the valve device comprises a pressure inlet, a tank outlet and a first electromagnetically actuated valve, and an outlet pressure of the adjustable hydraulic pump system is applied to the pressure inlet of the valve device,
• wherein the first fluid sensor detects an actual value of a fluid parameter of the adjustable hydraulic pump system and transmits the actual value of the fluid parameter to the electronic control unit,
• wherein the electronic control unit comprises a computer-based modeling of an overall dynamic of the adjustable hydraulic pump system,
• wherein the computer-based modeling of the overall dynamic of the adjustable hydraulic pump system comprises an artificial neural network which is fed with training data comprising measurement data and/or simulation data,
• wherein the artificial neural network comprises at least one output parameter,
• wherein the at least one output parameter is a predicted outlet pressure or a predicted outlet volume flow of the adjustable hydraulic pump system, and
• wherein the electronic control unit actuates the first electromagnetically actuated valve based on the actual value of the fluid parameter and based on the at least one output parameter of the artificial neural network.
