Design Of Fuzzy Logic Based Controller For Energy Efficient Operation In Building

Building energy management is a major R&D topic, as buildings account for about 32% of energy consumption worldwide. Design and implementation of controller for energy efficient operation in building is one of the methods to save the energy in the building. In this paper, a fuzzy logic based approach is used to design the energy management controller. Fuzzy logic has been widely used in the control engineering and many other fields of study. In the proposed approach, fuzzy logic is used to simulate the building load profile, and control the load of the appliance by flexibly choosing load scheduling. The controller would set a power threshold that cannot be exceeded, otherwise an on/off control of the home appliances would be invoked. In such a way, peak shaving of the power could be achieved. Using MATLAB-based graphical user interfaces, such fuzzy logic-based application could very well be implemented, reflecting on real-life scenarios.
