Multiple model and observer design for a water-based PV/T collector
Résumé
In this paper, a multiple thermal model for a water-based photovoltaic-thermal (PV/T) collector is constructed by mathematical transformation, using the boundedness of non-linear terms. Simulations have been performed and the results indicate that the convex polytopic transformation can accurately represent the non-linear model. Further, a Linear Matrix Inequality (LMI) approach is used to design an observer for estimating the states of the system. The efficiency and performance of the proposed observer in estimating the states of the system are shown through simulation.
