  • Method for determining a piston position in a hydraulic cylinder drive, method for operating an arrangement including a hydraulic cylinder drive, and mechanism for implementing the methods
    Patent number: 12674476
    Abstract: A method for determining a piston position of a piston in a hydraulic cylinder drive includes (i) providing a dynamic model of the cylinder drive, (ii) controlling driving of the cylinder drive with a control signal, (iii) detecting a real piston position of the piston, and (iv) adjusting parameters of the model on the basis of the real piston position. The model maps components of the cylinder drive and outputs a calculated piston position of the piston on the basis of detected operating parameters of the cylinder drive. A method of operating an arrangement having a corresponding hydraulic cylinder drive and a mechanism for implementing the methods are also disclosed herein.

  • Method for operating a hydraulic drive
    Patent number: 12331766
    Abstract: The disclosure relates to a method for operating a hydraulic drive which comprises a hydraulic consumer with a positionable piston in a cylinder which is connected to a tank at one connection via a pump of variable rotational speed and at another connection via a proportional valve, wherein a position of the piston is controlled using a model-based control in which a rotational speed of the pump is used as a manipulated variable and in which a position of the proportional valve is preset.
