Model-based predictive control of a solar reactor
Résumé
The present paper deals with the modelling and control of a solar reactor designedto produce syngas, by exploiting concentrated solar power. A model of the reactor based onthe thermodynamic equilibrium is developed. Two model-based predictive control strategiesare proposed: the first strategy (MPC strategy 1) aims to maintain the reactor's temperature atits nominal value whereas the second strategy (MPC strategy 2) aims to maintain the reactor'stemperature at its nominal value, while maximizing the use of solar energy. Finally, thesestrategies 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 theMPC controller to forecast errors is also studied by testing different DNI forecasting models
