Experimental implementation of UFAD regulation based on Robust Controlled Invariance

In this paper, we implement a temperature regulation strategy on a small-scale building equipped with Under-Floor Air Distribution (UFAD). Using a 0-dimensional model of the temperature variations in the building identified from experimental measurements, this strategy is based on the criteria of Robust Controlled Invariance, which give a characterization of the limits for a robust controller to keep the state of the system in an interval. These criteria are defined for monotone systems with bounded disturbances and thus are independent of the chosen control strategy.
