Abstract

Bilinear distributed parameter systems Fluid temperature Identification Iterative methods Laplace transform technique Newton-Raphson-Kantrovich method Solar collection system
This paper considers the parameter identification problem in solar collectors under full-flow condition. The fluid temperature profile in a solar energy collector is modeled by a bilinear distributed parameter system (The Klein plug-flow model). The distributed parameter system is reduced into a set of ordinary differential equations in frequency domain using the Laplace transform technique. The identifier minimizes iteratively the mean-square error between the measurements and the states predicted by the model at a certain geometrical point in the collector. The iterative method used is the Newton-Raphson-Kantrovich approach. The simulation studies using a microprocessor are illustrated.
