An Optimized Feedback Color Control for Multichannel LED Lighting System

In this paper we provide an Optimized feedback color control of multi-channel LEDs Lighting System. The proposed feedback color control system ensures that the desired lighting ambiance in a room is maintained, even when external lighting conditions change or there are disturbances. The system incorporates a 18 channel spectral sensor, a MIMO PI controller, an anti-windup algorithm, an efficient optimization algorithm and an array of colored LEDs. Thanks to its excellent performance, the experimental results validate the algorithm.
