A Hybrid Model and MIMO Control for Intelligent Buildings Temperature Regulation over WSN
Résumé
The aim of this paper is to propose a model-based feedback control strategy for Indoor temperature regulation in buildings equipped with under floor air distribution (UFAD). Supposing distributed sensing and actuation capabilities, a 0D model of the ventilation process is first derived, based on the thermodynamics properties of the flow. A state-space description of the process is then inferred, including discrete events modeled by Markovian processes. This results in a hybrid model with nonlinear components. The use of a wireless sensor network (WSN) and the resulting communication constraints are also discussed. A H\infty MIMO controller is finally proposed and shown to effectively handle the discrete and nonlinear perturbations.
