Data-Driven Passivity-Based Control Design for Modular DC Microgrids

This paper contains a new passivity-based control design approach for DC microgrids. The design is purely based on experimental data---bypassing the requirement of the network modeling. This approach permits the control of DC microgrids and preserve stability, despite of further interconnection of new passive loads and new passivity-based-controlled converters. This model-free approach generates control laws in a pure numerical way; bypassing the requirement of dealing with a high number of variables and equations, that naturally appear in an increasingly complex DC microgrid. Experimental results are presented to corroborate the advantages of our approach.
