Model-Based and Data-Driven Hierarchical Control and Topology Co-Design for Robust Networked Systems
Shirantha Welikala, Zihao Song, Hai Lin +1
In this paper, we consider a class of networked systems comprising an interconnected set of linear subsystems, disturbance inputs, and performance outputs. Using dissipativity theo…
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…
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…
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…
