Beschreibung
Zusammenfassung:	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.
