A Bilinear FSP-SPC in a solar desalination plant collector field

Abstract

This paper presents a Bilinear FSP-SPC to control the outlet temperature of a solar collector field. The process have a dead-time caused by multiple factors and requires an advanced control techniques to be controlled. This algorithm combines the numerical robustness typical of subspace-based methods with the robustness and performance of filtered Smith predictor based controllers. It uses a bilinear subspace predictor that contains the disturbance model and linearized at each sample period the forced response. The obtained results show that the proposed strategy gives good set point tracking and disturbance rejection considering dead time estimation errors.
