Optimal co-designs of communication and control in bandwidth-constrained cyber-physical systems

AUTOMATICA, 142.

By: N. Negi n & A. Chakrabortty n

author keywords: Linear optimal control; Structural optimization; Time-delay systems; Delay analysis; Bandwidth allocation
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.

Sparsity-promoting optimal control of cyber-physical systems over shared communication networks

AUTOMATICA, 122.

By: N. Negi n & A. Chakrabortty n

author keywords: Linear optimal control; Structural optimization; Time-delay systems; Delay analysis; Bandwidth allocation
TL;DR: A set of sparse H2 control designs under time-delays in the feedback and fair sharing of bandwidth among users under mixed-integer linear program (MILP) constraints is presented. (via Semantic Scholar)

Distributed control based power sharing strategy for an islanded AC microgrid

IET GENERATION TRANSMISSION & DISTRIBUTION, 13(4), 553–562.

By: N. Negi n, S. Sahoo* & S. Chakrabarti*

author keywords: centralised control; power distribution faults; distributed power generation; distributed control; power distribution control; distributed control; power sharing strategy; islanded AC microgrid; novel secondary control strategy; radial microgrid; end-to-end distributed energy resource interconnections; islanded conditions; sparse communication; centralised controller; distributed algorithm; desired power injection; DER bus; load change; remaining task; bus angle set points; DER units; actual power injections; accurate system wide power injection; respective DER base ratings; three-bus; three-DER system; microgrid ratings; system nominal ratings; correct power injection solution; accurate power
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.
