Abstract

In this study, different model-based controllers designed for the operation of a solar power plant are discussed and tested. A simplified physically based model of the plant was developed on the basis of energy balances, including solar radiation as an input, heat transferred by the flow of the oil used as a working medium and overall heat loss from the plant. Average outlet temperature of the collector field is the reference/set-point value, while volumetric flow rate of oil is the manipulation variable to the controller. Solar radiation, ambient temperature and temperature of the inlet oil to the collector field are assumed as disturbances. The model developed and identified is an internal part of the robust controller. The modelling and experimental results are presented, pointing out the applicability of robust internal model-based control.
