Hierarchical predictive control for multizone building
Résumé
This paper describes a dynamic modeling and control of a multizone building where the thermal exchange, the coupling between the areas and the human occupation energy are taken into account. The thermal regulation in the building is ensured by a HVAC (Heating, Ventilation and Air Conditioning) system in which many parameters are involved. The HVAC systems are the main equipment for human life, but they are sources of energy expenditure. The objectives of this research are to minimize energy consumption and keep users' convenience while aging on the HVAC control system. The whole management system is carried out in a distributed manner, by using a predictive controller. This latter must solve a problem for the local optimization with a partial knowledge of the behavior expected by the other controllers. Then, we consider hierarchical structure to design the controller for the main thermal power supply in order to offer the suitable thermal power demand for each zone satisfy the users needs. After a theoretical formalization of the approach, the effectiveness of the proposed results is highlighted in particular through simulation on Matlab/Simulink software.
