Robust voltage regulation of boost converters in DC microgrids

Questo articolo tratta la progettazione di uno schema di controllo robusto per la regolazione della tensione in reti in corrente continua. Lo schema di controllo proposto è stata verificato attraverso una microrete reale in corrente continua.

This paper deals with the design of a robust decentralized control scheme for voltage regulation in boost-based DC microgrids. The proposed solution consists of the design of a suitable manifold on which voltage regulation is achieved, even in presence of unknown load demand and modelling uncertainties.

A second order sliding mode control is used to constrain the state of the microgrid to this manifold by generating continuous control inputs that can be used as duty cycles of the power converters. The proposed control scheme has been validated through experiments on a real DC microgrid.
