Distributed Optimal Heating Control of Building Zones

This paper deals with distributed control of building zones heating with individual room mathematical model and corresponding controller, and iterative coordination towards the joint energy efficiency goal of a single building floor consisted of 23 rooms. The control structure exploits model predictive control, which is based on the calculation of the system control variable on the prediction horizon while respecting the imposed constraints. Such control approach is applied individually to each room and further coordinated together through the concept of distributed optimal control and the asymmetric projection algorithm. The distributed room temperature control is implemented within a realistic scenario of a living lab case study. The presented results show that model predictive control enables a trade-off between comfort and required energy. The distributed model predictive control provides the same results as the centralized version while additionally enables fast digitalization of the room, simple thermal model, and high user privacy.
