PID in Smart Buildings

This paper investigates a smart heat control system inside a household using a family of dynamic controllers called PID (Proportional Integrative Derivative), conducted with Wireless Sensor Networks (WSN). The laws of thermodynamics and other physical knowledge was used to model the effect that a heat exchanger has on the temperature of a room. Realistic simulations have been run to illustrate how a PID control system outperforms the traditional on-off approach, in terms of energy efficiency. Simulations shows that the PID controlled system is 28% more energy efficient than an on-off. This can make the future use of PIDs in home automation more common. Lastly a future extension to other systems is discussed
