PID in Smart Buildings

This paper investigates a smart heat control systeminside a household using a family of dynamic controllers calledPID (Proportional Integrative Derivative), conducted withWireless Sensor Networks (WSN). The laws of thermodynamicsand other physical knowledge was used to model the effect that aheat exchanger has on the temperature of a room. Realisticsimulations have been run to illustrate how a PID control systemoutperforms the traditional on-off approach, in terms of energyefficiency. Simulations shows that the PID controlled system is28% more energy efficient than an on-off. This can make thefuture use of PIDs in home automation more common. Lastly afuture extension to other systems is discussed
