Limitations and Performances of Robust Control Over WSN: UFAD Control in Intelligent Buildings
The aim of this paper is to propose a model-based feedback control strategy for indoor temperature regulation in buildings equipped with UnderFloor Air Distribution (UFAD). Supposing distributed sensing and actuation capabilities, a 0D model of the ventilation process is derived, based on the thermodynamics properties of the flow. A state-space description of the process is then inferred, including discrete events and nonlinear components. The use of a Wireless Sensor Network (WSN) and the resulting communication constraints with the IEEE 802.15.4 standard are discussed. Both synchronous and asynchronous transmissions are considered.
