Abstract

We consider distributed lighting control systems consisting of multiple asynchronous feedback controllers that adapt dimming of intelligent light source based on occupancy and illuminance value as measured by co-located occupancy and light sensors respectively. In an initial calibration step, the set-point at the light sensor for every controller is determined. Changes in reflectance due to factors like changes in occupancy and object characteristics modify the set-point, thus adversely affecting the illumination distribution from the lighting system. We propose a method for sensor set-point calibration and tracking and an associated lighting control algorithm. Initial calibration of set-points is achieved distributedly with light sources dimming according to a proposed sequence. We show that the proposed methods improve the illumination performance of the lighting system in event of reflectance changes.
