Abstract

In this article, a physical model of the building by thermoelectric analogy was developed. A detailed and simplified nonlinear model was obtained. Experimental data were collected at the laboratory site with a weather station equipped with a computer to measure the external and internal climatic variables. A linear approach was then implemented on this nonlinear model to prepare it for controlling of the building's internal microclimate. After the two linearization methods were used, linearization by indirect Lyapunov method and a modal simplification of the original nonlinear system were conducted. Validation, calculation and simulation were performed under the MATLAB/Simulink environment.
