Abstract

Linear Fresnel Reflector (LFR) systems for Direct Steam Generation (DSG) exhibit strong nonlinear and transient dynamics due to diurnal solar variability, making real-time control challenging. To address this, a Gated Recurrent Unit (GRU)-based deep neural network surrogate replaces the computationally intensive first-principles LFR model and is embedded within a Nonlinear Model Predictive Control (NMPC) framework for fast prediction. Trained using scheduled sampling, the surrogate achieves prediction fits of 87.39% for steam quality and 90.55% for LFR outlet pressure. The GRU-based LFR model is integrated with a first-principles Steam Drum (SD) model in a centralized NMPC scheme to regulate steam quality and drum water level. Closed-loop simulations under varying solar insolation with cloud cover demonstrate effective tracking of time-varying setpoints, validating the proposed hybrid predictive control approach.
