Primal-dual algorithm for distributed optimization: A dissipativity-based perspective
Weijian Li, Panos J. Antsaklis, Hai Lin
We study a continuous-time primal-dual algorithm for distributed optimization with nonconvex local cost functions over weight-unbalanced digraphs, and analyze its performance from…
MA-enhanced Mixed Near-field and Far-field Covert Communications
Chao Zhou, Changsheng You, Cong Zhou +2
In this paper, we propose to employ a modular-based movable extremely large-scale array (XL-array) at Alice for enhancing covert communication performance. Compared with existing w…
Funnel-Based Online Recovery Control for Nonlinear Systems With Unknown Dynamics
Zihao Song, Shirantha Welikala, Panos J. Antsaklis +1
In this paper, we focus on recovery control of nonlinear systems from attacks or failures. The main challenges of this problem lie in (1) learning the unknown dynamics caused by at…
Hierarchical Analysis and Control of Epidemic Spreading over Networks using Dissipativity and Mesh Stability
Shirantha Welikala, Hai Lin, Panos J. Antsaklis
Analyzing and controlling spreading processes are challenging problems due to the involved non-linear node (subsystem) dynamics, unknown disturbances, complex interconnections, and…
Mesh Stability Guaranteed Rigid Body Networks Using Control and Topology Co-Design
Zihao Song, Shirantha Welikala, Panos J. Antsaklis +1
Merging and splitting are of great significance for rigid body networks in making such networks reconfigurable. The main challenges lie in simultaneously ensuring the compositional…
Graph Neural Network-Based Distributed Optimal Control for Linear Networked Systems: An Online Distributed Training Approach
Zihao Song, Shirantha Welikala, Panos J. Antsaklis +1
In this paper, we consider the distributed optimal control problem for discrete-time linear networked systems. In particular, we are interested in learning distributed optimal cont…
Inventory Consensus Control in Supply Chain Networks using Dissipativity-Based Control and Topology Co-Design
Shirantha Welikala, Hai Lin, Panos J. Antsaklis
Recent global and local phenomena have exposed vulnerabilities in critical supply chain networks (SCNs), drawing significant attention from researchers across various fields. Typic…
Dissipativity-Based Decentralized Co-Design of Distributed Controllers and Communication Topologies for Vehicular Platoons
Shirantha Welikala, Zihao Song, Panos J. Antsaklis +1
Vehicular platoons provide an appealing option for future transportation systems. Most of the existing work on platoons separated the design of the controller and its communication…
Coordination and Control of Distributed Discrete Event Systems under Actuator and Sensor Faults
Jin Dai, Hai Lin
We investigate the coordination and control problems of distributed discrete event systems that are composed of multiple subsystems subject to potential actuator and/or sensor faul…
