Pressurized water temperature control of a fresnel collector field-type solar cooling system using explicit model predictive control

Abstract

This paper addresses the design of an explicit model predictive controller for the outlet water temperature control of a solar cooling plant system that uses a field of Fres-nel collectors. Solving multi-parametric quadratic programs (mpQP) to obtain explicit solutions to constrained model predictive control (MPC) problems enables the offline design before the MPC controller is implemented, e.g., on a standard programmable logic controller. The simulation result shows the feasibility of the proposed control design for such a system. This is implementable on industrial application-based hardware platforms where computational and memory resources are limited.
