Abstract :
This paper presents a dynamical model for a Parabolic Trough (PT) reflector. In particular, this model describes the behavior of the output steam enthalpy and can be used to develop a control strategy for the coupling with a conventional power plant such as a Combined Cycle Power Plant (CCPP). The modeling uses the principle of a moving-boundary configuration with a two-phase flow region, and a nonlinear dynamical state space description is obtained. A linearization-based approach with an observer is proposed for a LQR control law that is validated on the nonlinear model.
