Abstract

This article presents a feedback linearization control of a distributed solar collector field, which main purpose is to heat a fluid using the energy provided by the solar irradiation. The control objective is to track an outlet temperature reference manipulating the fluid flow trying to attenuate the effect of disturbances (mainly radiation and inlet temperature). A feedback linearization technique has been developed and implemented to control this nonlinear plant by merging both feedforward and feedback control. The design of the feedback controller is performed based on a linear simplified version of the system. Experiments in the real plant are shown
