Passivity, No-Regret, and Convergent Learning in Contractive Games
Hassan Abdelraouf, Georgios Piliouras, Jeff S. Shamma
We investigate the interplay between passivity, no-regret, and convergence in contractive games for various learning dynamic models and their higher-order variants. Our setting is…
Polynomial Lyapunov Functions and Invariant Sets from a New Hierarchy of Quadratic Lyapunov Functions for LTV Systems
Hassan Abdelraouf, Eric Feron, Jeff S. Shamma
We introduce a new class of quadratic functions based on a hierarchy of linear time-varying (LTV) dynamical systems. These quadratic functions in the higher order space can be also…
Can Competition Outperform Collaboration? The Role of Misbehaving Agents
Luca Ballotta, Giacomo Como, Jeff S. Shamma +1
We investigate a novel approach to resilient distributed optimization with quadratic costs in a multi-agent system prone to unexpected events that make some agents misbehave. In co…
Competition-Based Resilience in Distributed Quadratic Optimization
Luca Ballotta, Giacomo Como, Jeff S. Shamma +1
This paper proposes a novel approach to resilient distributed optimization with quadratic costs in a networked control system (e.g., wireless sensor network, power grid, robotic te…
Safe Adaptive Learning-based Control for Constrained Linear Quadratic Regulators with Regret Guarantees
Yingying Li, Subhro Das, Jeff Shamma +1
We study the adaptive control of an unknown linear system with a quadratic cost function subject to safety constraints on both the states and actions. The challenges of this proble…
Network Effects on Robustness of Dynamic Systems
Ketan Savla, Jeff S. Shamma, Munther A. Dahleh
We review selected results related to robustness of networked systems in finite and asymptotically large size regimes, under static and dynamical settings. In the static setting, w…
Herdability of Linear Systems Based on Sign Patterns and Graph Structures
Sebastian F Ruf, Magnus Egerstedt, Jeff S. Shamma
We consider the notion of herdability, a set-based reachability condition, which asks whether the state of a system can be controlled to be element-wise larger than a non-negative…
Herding Positive, Complex Networks
Sebastian F. Ruf, Magnus Egersted, Jeff S. Shamma
The problem of controlling complex networks is of interest to disciplines ranging from biology to swarm robotics. However, controllability can be too strict a condition, failing to…
Herdable Systems Over Signed, Directed Graphs
Sebastian F. Ruf, Magnus Egerstedt, Jeff S. Shamma
This paper considers the notion of herdability, a set-based reachability condition, which asks whether the state of a system can be controlled to be element-wise larger than a non-…
Communication-Free Distributed Coverage for Networked Systems
A. Yasin Yazicioglu, Magnus Egerstedt, Jeff S. Shamma
In this paper, we present a communication-free algorithm for distributed coverage of an arbitrary network by a group of mobile agents with local sensing capabilities. The network i…
