Distributed Optimization with Coupled Constraints over Time-Varying Digraph
Yeong-Ung Kim, Hyo-Sung Ahn
In this paper, we develop a distributed algorithm for solving a class of distributed convex optimization problems where the local objective functions can be a general nonsmooth fun…
Controllable Subspaces in Structured Networks of Hierarchical Directed Acyclic Graphs: Controllability of Individual Nodes
Nam-Jin Park, Yeong-Ung Kim, Koog-Hwan Oh +1
Within the context of structured networks, this paper introduces the concept of the Fixed Strongly Structurally Controllable Subspace (FSSCS), enabling a comprehensive characteriza…
Autonomous Cooperative Levels of Multiple-Heterogeneous Unmanned Vehicle Systems
Yoo-Bin Bae, Yeong-Ung Kim, Jun-Oh Park +1
As multiple and heterogenous unmanned vehicle systems continue to play an increasingly important role in addressing complex missions in the real world, the need for effective coope…
Fixed Node Determination and Analysis in Directed Acyclic Graphs of Structured Networks
Nam-jin Park, Yeong-Ung Kim, Hyo-Sung Ahn
This paper explores the conditions for determining fixed nodes in structured networks, specifically focusing on directed acyclic graphs (DAGs). We introduce several necessary and s…
