Fuzzy logic controller for regulating the indoor temperature

In recent times, globalization and energy efficiency policies have further required temperature control applications in different daily activities, especially with the greenhouse effect. In residential buildings, water and living space heating consumes most of the primary energy. The paper presents a method to keeping the comfort temperature in living space by using an approach based on an artificial intelligence technique, namely fuzzy logic. The support for the proposed method is an electrical hot-water radiator heating system with a tankless heater. The fuzzy logic controller makes a continuous regulation of the indoor temperature by adapting the temperature of the heating agent regarding the indoor and exterior temperature. To validate and test the proposed method, MATLAB-Simulink was employed. The comparison with an On/Off controller that is the most used control device due to financial benefits showed the efficiency of the fuzzy logic controller.
