Title
(EN) METHOD FOR CONTROLLING AN ACTUATOR
(FR) PROCÉDÉ POUR COMMANDER UN ACTIONNEUR
Abstract
(EN) A method for controlling an actuator, such as the type used to drive valves, vanes, and other variable position devices. In one exemplary embodiment, a method may improve the accuracy of actuator feedback by periodically or dynamically resetting the position of a lower hard stop, which can then be used as a future point of reference.
(FR) L'invention porte sur un procédé pour commander un actionneur, par exemple du type utilisé pour actionner des vannes, des aubes, et d'autres dispositifs à position variable. Dans un exemple de mode de réalisation, un procédé peut améliorer la précision de rétroaction d'actionneur par redéfinition périodique ou dynamique de la position d'un arrêt dur inférieur, qui peut ensuite être utilisé comme futur point de référence.
