Résumé

This article presents the results from the controlling of the thermal environment of an enclosed space using Euler-Lagrange equations in a variable control context, and compares it with three semi-empirical controller settings. Thermodynamic characteristics of the space of the administrative building equipped with convectors, disseminating heat energy supplied by steam, provided its mathematical model, which is fully commandable and observable. The model of the enclosed space -single-zone room- was reduced to the desired order dimension applied on the model's transfer function. Comparing the outputs with measurements and the results obtained for each simulation case showed energy savings and the optimal variable control method itself as an effective alternative, if Lagrange multipliers in Euler-Lagrange equations could be solved separately apart from model state-form variables.
