Model-based predictive control of a solar reactor
Résumé
The present paper deals with the modelling and control of a solar reactor designed
to produce syngas, by exploiting concentrated solar power. A model of the reactor based on
the thermodynamic equilibrium is developed. Two model-based predictive control strategies
are proposed: the first strategy (MPC strategy 1) aims to maintain the reactor's temperature at
its nominal value whereas the second strategy (MPC strategy 2) aims to maintain the reactor's
temperature at its nominal value, while maximizing the use of solar energy. Finally, these
strategies are compared to a reference strategy, which is based on a combination of a rulebased controller and an adaptive PID controller with optimized gains. The robustness of the
MPC controller to forecast errors is also studied by testing different DNI forecasting models
