Generalized Predictive Controller Applied in a Bidirectional DC-DC Converter

Abstract

This work proposes the project of the Generalized Predictive Controller (GPC), this is applied to a bidirectional converter, whose topology is the non-isolated Buck and Boost derived bidirectional DC-DC, present on a DC Nanogrid. The system consists of a primary bus, represented by Vdc, with high voltage, which is feeded by a renewable energy source that generates 175 V and a secondary source, represented by VBatt, with low voltage from a 48 V battery. The objective is to develop robustness and performance analysis, and ensure reference tracking and rejection of disturbance of this predictive controller when used in a bidirectional converter present in the aforementioned situation. In addition to analyzing how the control weighting factor interferes in the robustness and performance of this controller in this situation.
