TL;DR: This work addresses the problem of sparsity-promoting optimal control of cyber-physical systems (CPSs) in the presence of communication delays by co-designing an optimal combination of these two delays and a sparse state-feedback controller while respecting a given bandwidth cost constraint.

TL;DR: This study presents a novel secondary control strategy for a radial microgrid with end-to-end distributed energy resource (DER) interconnections, operating under islanded conditions, which utilises sparse communication and precludes the presence of a centralised controller.
