Fuzzy quasi LPV model for a cross flow heat exchanger

This paper presents a new dynamic model called fuzzy quasi LPV model which simulate accurately the temperature and flow transients in a cross flow heat exchanger (CFHX). Motivated by the ability of fuzzy tools to approximate and management of nonlinearities, and based on the interpretation of parameters in Takagi-Sugeno (TS) models, we present a new procedure for identifying nonlinear models of linear parameter varying type. The fuzzy quasi LPV model is compared to a numerical model of a cross flow heat exchanger. Comparisons indicate that the developed fuzzy quasi LPV model is capable of predicting the transient performance of the heat exchangers satisfactorily.
