Robust Distributed Fixed-Time Economic Dispatch under Time-Varying Topology
Mayank Baranwal, Kunal Garg, Dimitra Panagou +1
The centralized power generation infrastructure that defines the North American electric grid is slowly moving to the distributed architecture due to the explosion in use of renewa…
Safety-Critical Adaptive Control with Nonlinear Reference Model Systems
Ehsan Arabi, Kunal Garg, Dimitra Panagou
In this paper, a model reference adaptive control architecture is proposed for uncertain nonlinear systems to achieve prescribed performance guarantees. Specifically, a general non…
Finite-Time Stability of Hybrid Systems: A Multiple Generalized Lyapunov Functions Approach
Kunal Garg, Dimitra Panagou
This paper studies finite-time stability of a class of hybrid systems. We present sufficient conditions in terms of multiple generalized Lyapunov functions for the origin of the hy…
Resilient Leader-Follower Consensus to Arbitrary Reference Values in Time-Varying Graphs
James Usevitch, Dimitra Panagou
Several algorithms in prior literature have been proposed which guarantee consensus of normally behaving agents in a network that may contain adversarially behaving agents. These a…
Resilient Leader-Follower Consensus with Time-Varying Leaders in Discrete-Time Systems
James Usevitch, Dimitra Panagou
The problem of consensus in the presence of adversarially behaving agents has been studied extensively in the literature. The proposed algorithms typically guarantee that the conse…
Fixed-time Control under Spatiotemporal and Input Constraints: A Quadratic Program Based Approach
Kunal Garg, Ehsan Arabi, Dimitra Panagou
In this paper, we present a control synthesis framework for a general class of nonlinear, control-affine systems under spatiotemporal and input constraints. First, we study the pro…
Herding an Adversarial Swarm in an Obstacle Environment
Vishnu S. Chipade, Dimitra Panagou
This paper studies a defense approach against a swarm of adversarial agents. We employ a closed formation (`StringNet') of defending agents around the adversarial agents to restric…
Prescribed-time convergence with input constraints: A control Lyapunov function based approach
Kunal Garg, Ehsan Arabi, Dimitra Panagou
In this paper, we present a control framework for a general class of control-affine nonlinear systems under spatiotemporal and input constraints. Specifically, the proposed control…
Herding an Adversarial Attacker to a Safe Area for Defending Safety-Critical Infrastructure
Vishnu S Chipade, Dimitra Panagou
This paper investigates a problem of defending safety-critical infrastructure from an adversarial aerial attacker in an urban environment. A circular arc formation of defenders is…
A Hybrid Approach to Persistent Coverage in Stochastic Environments
William Bentz, Dimitra Panagou
This paper considers the persistent coverage of a 2-D manifold that has been embedded in 3-D space. The manifold is subject to continual impact by intruders which travel at constan…
Control-Lyapunov and Control-Barrier Functions based Quadratic Program for Spatio-temporal Specifications
Kunal Garg, Dimitra Panagou
This paper presents a method for control synthesis under spatio-temporal constraints. First, we consider the problem of reaching a set in a user-defined or prescribed time .…
Determining r- and (r,s)-Robustness of Digraphs Using Mixed Integer Linear Programming
James Usevitch, Dimitra Panagou
There has been an increase in the use of resilient control algorithms based on the graph theoretic properties of - and -robustness. These algorithms guarantee consensus o…
Finite-Time Stability of Switched and Hybrid Systems with Unstable Modes
Kunal Garg, Dimitra Panagou
In this work, we study finite-time stability of switched and hybrid systems in the presence of unstable modes. We present sufficient conditions in terms of multiple Lyapunov functi…
