A 2DOF Thermosolar Concentrator Proposal: Solar Tracking and Disturbance Rejection Using Proportional Defocus.
Abstract
In this work, we propose two-degree-of-freedom linear Fresnel solar collectors and implement a DTC-GPC for conceptual validation of it use. The equipment modification is able to vary the power density in the receiver using a proportional geometric defocus besides the conventional solar tracking. Henceforth, the impact of adding this new manipulated variable over a DTC-GPC controller is evaluated on a desalination plant validated model. The idea results in a faster actuator which provides both, better performance and operation under constraints.
