Abstract
This article proposes a real-time light-energy saving control technique to reduce unnecessary light-energy consumption (LEC) for varying lighting environment, through regulating brightness of illuminative lamps while providing the expect illumination level. Considering the influence of environmental conditions, a fractional-order Newton-based extremum seeking control (ESC) method in the proposed technique is developed to enhance the tracking accuracy and convergence speed. It can result in the high efficient lighting system and the rapid track of minimum LEC. Moreover, it significantly reduces the impact of selecting an arbitrary Hessian matrix on tracking speed of the algorithm, which is the main drawback in the most conventional ESC algorithms. Experimental results reveal that the proposed method has the ability to track the available minimum LEC under changing environmental conditions.
