Abstract

A predictive control system was applied to a lowcost flat-plate solar collector. The system’s objective was to track desired setpoints and reject external disturbances. However, due to physical constraints of the system, achieving temperatures above 55°C became a challenge, resulting in a decrease in controller performance. Nonetheless, in a majority of cases, the objective was still met. The article describes the tools used and limitations encountered during simulations. In one of the experiments, it was possible to bring the controlled variable to the setpoints in approximately 30 seconds. The results obtained confirmed the efficiency and robustness of the predictive controller, even when applied to small systems with few degrees of freedom.
