Networked PID Controller Design for a Heating System

This work studies the issue of remotely controlling a single room’s temperature using a central heating system. The models of the components of the heating system setup are derived by equivalent electric circuits. The combined nonlinear description of the process is used to produce a linear approximant. A Proportional, Integral plus Derivative (PID) controller, located at a considerable distance from the process and receiving measurements and transmitting actuation signals via a wireless network, is designed based on the linear approximant and towards room temperature control. A metaheuristic approach, satisfying stability, approximate model matching, asymptotic command following, and disturbance attenuation, is used to calculate the controller parameters. The suggested scheme’s performance is illustrated through simulations.
