Designing and Implementing a Lighting Control System Based on Constrained Info-Fuzzy, to Save Energy and Satisfy Users

Considering that lighting plays an important role in energy consumption in buildings, extensive studies have been conducted in recent years to increase efficiency and thus reduce the cost of lighting. However, it should be noted that such efforts can achieve complete success when the behavior patterns and level of user satisfaction are also considered. With this approach, in this article, a control system based on INFO-FUZZY is proposed to save energy and provide user satisfaction, considering the behavioral patterns of residents. The proposed lighting control system is flexible, adjustable continuous, and highly accurate. The efficiency of the proposed lighting system in the office environment of the university has been evaluated in real-time by considering three desks and two scenarios. The experimental results confirm the high efficiency and high adjustability of the proposed control system. Also, the results show that the error rate in the four criteria of ISE, ITSE, IAE, and ITAE in the proposed INFO-FUZZY algorithm has been reduced favorably compared to the GA-FUZZY algorithm. This reduction rate in scenario 1 is 6.56, 12.2, 18.85%, and 94.83%, respectively, and in scenario 2, it is 14.56, 16.67, 20.45%, and 95.03%, respectively, which confirms the high efficiency of the proposed control system.
