Máquina minera y método para controlar el movimiento de un elemento móvil de una máquina minera
A method (1000) for controlling movement of a movable element of a mining machine is provided. The method comprises providing (1010) a relation between control values for a hydraulic valve arranged to affect a movement of the movable element and a parameter representative of the (resulting) movement of the movable element. The method further comprises receiving (1020) an input representative of a desired movement of the movable element. The method further comprises obtaining (1030) a control value for the hydraulic valve based on the relation and using a parameter value corresponding to the desired movement and operating (1040) the hydraulic valve with a control signal using the obtained control value. The method further comprises obtaining (1050), from a feedback mechanism, a feedback relative to the movement of the movable element resulting from operating the hydraulic valve with the control signal, determining (1060) a correction value based on said desired movement and the feedback, and updating (1090) at least a part of the relation based on the correction value.
