Tracking the Minimum Energy Consumption for the Lighting System though Modified Extremum Seeking Method.

This paper investigates how to track a minimum energy consumption in the lighting system despite of environmental variations. A hardware-in-the-loop prototype of an adaptive minimum energy usage for lighting control is developed, designed and built. A modified extremum seeking control algorithm is proposed to minimize energy usage in the lighting system, while a backstepping controller is employed to maintain a desired light level. The hardware-in-the-loop experimental results are given to show the practicality and effectiveness of the proposed control method. [ABSTRACT FROM AUTHOR]
