Title (EN) IMPLEMENT CONTROL BASED ON SURFACE-BASED COST FUNCTION AND NOISE VALUES
(FR) COMMANDE D'OUTIL BASÉE SUR DES VALEURS DE FONCTION DE COÛT BASÉE SUR LA SURFACE ET DE BRUIT
Abstract:
(EN) An earthmoving machine comprises a sensor, an implement, and control architecture comprising a controller and configured to facilitate movement in response to a signal indicative of a measured implement position and an implement control value comprising a gain value associated with implement speed. The controller is programmed to execute machine readable instructions to generate a surface-based cost function (SBCF) value based on the signal, determine whether the SBCF value is acceptable to lock the gain value, and generate a noise value that is based on an error between the signal and a target signal when the SBCF value is unacceptable, determine whether the noise value is acceptable to lock the gain value, adjust the gain value to control the implement speed when the noise value is unacceptable until the SBCF value or the noise value is acceptable, and operate the machine based on the locked gain value.
(FR) L'invention concerne une machine de terrassement comprenant un capteur, un outil, et une architecture de commande comprenant un dispositif de commande et conçue pour faciliter le déplacement en réponse à un signal indiquant une position d'outil mesurée et une valeur de commande d'outil comprenant une valeur de gain associée à la vitesse de l'outil. Le dispositif de commande est programmé pour exécuter des instructions lisibles par machine pour générer une valeur de fonction de coût basée sur la surface (SBCF) sur la base du signal, pour déterminer si la valeur SBCF est acceptable afin de verrouiller la valeur de gain, et pour générer une valeur de bruit basée sur une erreur entre le signal et un signal cible lorsque la valeur SBCF est inacceptable, pour déterminer si la valeur de bruit est acceptable afin de verrouiller la valeur de gain, pour régler la valeur de gain afin de commander la vitesse de l'outil lorsque la valeur de bruit est inacceptable jusqu'à ce que la valeur SBCF ou la valeur de bruit soit acceptable, et pour faire fonctionner la machine en fonction de la valeur de gain verrouillée.
