- © 2020 IEEE.This paper focuses on the control design of DC-DC converters delivering power into energy distribution networks. The scenario where the destabilizers of the system called constant power loads (CPLs) are presented. The idea of the proposed scheme is to take advantage of the so-called persistency of excitation conditions, which is used to elaborate a controller without the need for large mathematical models. The proposed data-driven approach can guarantee stability by solving a set of Lyapunov Linear Matrix Inequalities (LMIs). The stabilizing control scheme was designed using the linear difference systems and quadratic difference forms (QdF) concepts of behavioral system theory. Besides, a comparison between simulation and experimental results are presented to validate the theoretical design and illustrate the benefits of this scheme.
