Patent

CA 2708980

The present invention provides a method and apparatus for digitally controlling a lighting device which enables a desired lighting device operational set point to be reached in a rapid manner while substantially reducing overshoot and oscillation about the desired lighting device operational set point. In particular the present invention is enabled by a PID controller configured to vary the PID controller parameters based on a relationship based at least in part on the desired lighting device operational set point, the present lighting device operational point or both.

La présente invention concerne un procédé et appareil de commande numérique d'un dispositif d'éclairage permettant d'obtenir rapidement une valeur de consigne opérationnelle souhaitée d'un dispositif d'éclairage tout en réduisant sensiblement le dépassement et l'oscillation autour de la valeur de consigne opérationnelle du dispositif d'éclairage. En particulier, la présente invention est activée par un contrôleur d'identification de paramètres (PID)configuré pour varier les paramètres du contrôleur PID en fonction d'une relation basée au moins en partie sur la valeur de consigne opérationnelle du dispositif d'éclairage, la valeur opérationnelle actuelle du dispositif d'éclairage ou les deux.
