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…

Data-Driven Linear Quadratic Control Using Output-Feedback via Non-Minimal Realization

Weijian Li, Bowen Yi, Panos J. Antsaklis +1

In this paper, we investigate a continuous-time linear quadratic control problem for systems with unknown matrices, where only input-output data are available. We propose an output…

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…

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…
