Transfer functions of solar collectors for dynamical analysis and control design

In view of system efficiency and environmental protection, it is of primary importance to harvest solar energy better and better for example by means of developing solar collectors. Mathematical modelling is the theoretically established tool for it, for example with using the collector transfer functions. Knowing the transfer functions, the collector outlet temperature can be predicted as a function of the input variables (solar irradiance, inlet temperature, environment temperature), furthermore, collector control can be effectively designed based on the well-tried methods of control engineering.
