Duty cycle control on compressor of split air conditioners using internet of things embedded in fuzzy-PID

Abstract

Internet of things (IoT) makes every object have a representation in the virtual world that allows us to monitor and control them in the cyberspace. Monitoring of environmental conditions, rooms, and air conditioner controls can be used to find out and develop indoor room control strategies to be more efficient and comfortable for occupants. However, environmental conditions affect the dynamics of the system and its controller functions. This paper proposed a new approach to control room temperature through the control of the AC compressor duty cycle using IoT. Hybrid Fuzzy-PID (Proportional-Integral-Derivative) as a control algorithm that is embedded on the IoT platform. The algorithm determines optimal PID control parameters and adjusts them according to environmental conditions. Intelligent control proposed is applied to save energy and regulate the comfort of the room for residents. Finally, the Hybrid Fuzzy-PID and IoT approach allow us to achieve 50% energy savings in comfort that can be tolerated by occupants of the room.
