A Stochastic Binary Vertex-Triggering Resetting Algorithm for Global Synchronization of Pulse-Coupled Oscillators
Muhammad U. Javed, Jorge I. Poveda, Xudong Chen
In this paper, we propose a novel stochastic binary resetting algorithm for networks of pulse-coupled oscillators (or, simply, agents) to reach global synchronization. The algorith…
Scalable Resetting Algorithms for Synchronization of Pulse-Coupled Oscillators over Rooted Directed Graphs
Muhammad U. Javed, Jorge I. Poveda, Xudong Chen
We study the problem of robust global synchronization of pulse-coupled oscillators (PCOs) over directed graphs. It is known that when the digraphs are strongly connected, global sy…
Sparse Linear Ensemble Systems and Structural Controllability
Xudong Chen
The paper introduces and solves a structural controllability problem for continuum ensembles of linear time-invariant systems. All the individual linear systems of an ensemble are…
Controllability Issues of Linear Ensemble Systems over Multi-dimensional Parameterization Spaces
Xudong Chen
We address an open problem in ensemble control: Whether there exist controllable linear ensemble systems over multi-dimensional parameterization spaces? We provide a negative resul…
Global Synchronization of Clocks in Directed Rooted Acyclic Graphs: A Hybrid Systems Approach
Muhammad U. Javed, Jorge I. Poveda, Xudong Chen
In this paper, we study the problem of robust global synchronization of resetting clocks in multi-agent networked systems, where by robust global synchronization we mean synchroniz…
Ensemble Observability of Bloch Equations with Unknown Population Density
Xudong Chen
We introduce in the paper a novel observability problem for a continuum ensemble of nonholonomic control systems with unknown population density. We address the problem by focussin…
Joint Actuator-sensor Design for Stochastic Linear Systems

We investigate the joint actuator-sensor design problem for stochastic linear control systems. Specifically, we address the problem of identifying a pair of sensor and actuator whi…
Controllability of Continuum Ensemble of Formation Systems over Directed Graphs
Xudong Chen
We propose in the paper a novel framework for using a common control input to simultaneously steer an infinite ensemble of networked control systems. We address the problem of co-d…
Structure Theory for Ensemble Controllability, Observability, and Duality
Xudong Chen
Ensemble control deals with the problem of using a finite number of control inputs to simultaneously steer a large population (in the limit, a continuum) of control systems. Dual t…
Optimal Capacity Allocation for Sampled Networked Systems
Xudong Chen, M. -A. Belabbas, Tamer Basar
We consider the problem of estimating the states of weakly coupled linear systems from sampled measurements. We assume that the total capacity available to the sensors to transmit…
Optimal actuator placement for minimizing the worst-case control energy
Xudong Chen, M. -A. Belabbas
We consider the actuator placement problem for linear systems. Specifically, we aim to identify an actuator which requires the least amount of control energy to drive the system fr…
Distributed Evaluation and Convergence of Self-Appraisals in Social Networks
Xudong Chen, Ji Liu, M. -A. Belabbas +2
We consider in this paper a networked system of opinion dynamics in continuous time, where the agents are able to evaluate their self-appraisals in a distributed way. In the model…
A Remark on Formation Control with Triangulated Laman Graphs: Genericity of Equivariant Morse Functions
Xudong Chen
This paper, as a continuing work of [1], focus on establishing the fact that if we equip a reciprocal multi-agent (RMA) system with a triangulated Laman graph (TLG), then the assoc…
Consensus with Linear Objective Maps
Xudong Chen, M. -A. Belabbas, Tamer Basar
A consensus system is a linear multi-agent system in which agents communicate to reach a so-called consensus state, defined as the average of the initial states of the agents. Cons…
Swarm Aggregation under Fading Attractions
Xudong Chen
Gradient descent methods have been widely used for organizing multi-agent systems, in which they can provide decentralized control laws with provable convergence. Often, the contro…
Formation Control with Triangulated Laman Graphs
Xudong Chen, M. -A. Belabbas, Tamer Basar
Formation control deals with the design of decentralized control laws that stabilize agents at prescribed distances from each other. We call any configuration that satisfies the in…
Controllability of Formations over Time-varying Graphs
Xudong Chen, M. -A. Belabbas, Tamer Basar
In this paper, we investigate the controllability of a class of formation control systems. Given a directed graph, we assign an agent to each of its vertices and let the edges of t…

Xudong Chen
In this paper, we investigate a decentralized formation control algorithm for an undirected formation control model. Unlike other formation control problems where only the shape of…
