• ### Leader Tracking of Euler-Lagrange Agents on Directed Switching Networks Using A Model-Independent Algorithm

Publication Year: 2018, Page(s): 1
| | PDF (2303 KB)

In this paper, we propose a discontinuous distributed model-independent algorithm for a directed network of Euler-Lagrange agents to track the trajectory of a leader with non-constant velocity. We initially study a fixed network and show that the leader tracking objective is achieved semi-globally exponentially fast if the graph contains a directed spanning tree. By model-independent, we mean that... View full abstract»

• ### Hybrid interconnection of iterative bidding and power network dynamics for frequency regulation and optimal dispatch

Publication Year: 2018, Page(s): 1
| | PDF (3137 KB)

This paper considers a real-time electricity market involving an independent system operator (ISO) and a group of strategic generators. The ISO operates a market where generators bid prices at which they are willing to provide power. The ISO makes power generation assignments with the goal of solving the economic dispatch problem and regulating the network frequency. We propose a multi-rate hybrid... View full abstract»

• ### Tracking and Control of Gauss-Markov Processes over Packet-Drop Channels with Acknowledgments

Publication Year: 2018, Page(s): 1
| | PDF (1425 KB)

We consider the problem of tracking the state of Gauss-Markov processes over rate-limited erasure-prone links. We concentrate first on the scenario in which several independent processes are seen by a single observer. The observer maps the processes into finite-rate packets that are sent over the erasure-prone links to a state estimator, and are acknowledged upon packet arrivals. The aim of the st...

• ### Time-Varying Output Formation-Containment of General Linear Homogeneous and Heterogeneous Multi-Agent Systems

Publication Year: 2018, Page(s): 1
| | PDF (1884 KB)

This paper investigates the time-varying output formation-containment control of general linear homogeneous and heterogeneous multi-agent systems (MAS). This control aims at making each follower's output reach an agreement on the time-varying formation reference, namely, the centroid of the multiple leaders' outputs, and keep a predefined time-varying offset with respect to it. Distributed static ... View full abstract»

• ### Nonovershooting Cooperative Output Regulation of Linear Multi-Agent Systems by Dynamic Output Feedback

Publication Year: 2018, Page(s): 1
| | PDF (1123 KB)

We consider the problem of cooperative output regulation for linear multi-agent systems. A distributed dynamic output feedback design method is presented that solves the cooperative output regulation problem and also ensures that all agents track the desired reference signal without overshoot in their transient response.

• ### Output synchronization of unknown heterogeneous agents via distributed model reference adaptation

Publication Year: 2018, Page(s): 1
| | PDF (1343 KB)

This work presents a distributed model reference adaptive methodology for output synchronization of heterogeneous linear agents with unknown dynamics. We consider a setting in which the control input is communicated among neighbors, instead of observer variables. For those agents that can access the signals of the reference model, classical model reference adaptation laws lead to leader synchroniz... View full abstract»

• ### EXPOSE the Line Failures following a Cyber-Physical Attack on the Power Grid

Publication Year: 2018, Page(s): 1
| | PDF (1247 KB)

Recent attacks on power grids demonstrated their vulnerability to cyber and physical attacks. To analyze this vulnerability, we study cyber-physical attacks that affect both the power grid physical infrastructure and its underlying Supervisory Control And Data Acquisition (SCADA) system. We assume that an adversary attacks an area by: (i) disconnecting some lines within that area, and (ii) obstruc... View full abstract»

• ### Locality in Network Optimization

Publication Year: 2018, Page(s): 1
| | PDF (564 KB)

In probability theory and statistics notions of correlation among random variables, decay of correlation, and bias-variance trade-off are fundamental. In this work we introduce analogous notions in optimization, and we show their usefulness in a concrete setting. We propose a general notion of correlation among variables in optimization procedures that is based on the sensitivity of optimal points... View full abstract»

• ### Mitigation and Recovery from Cascading Failures in Interdependent Networks under Uncertainty

Publication Year: 2018, Page(s): 1
| | PDF (2689 KB)

The interdependency of multiple networks makes today's infrastructures more vulnerable to failures. Prior works mainly focused on robust network design and recovery strategies after failures, given complete knowledge of failure location. Nevertheless, in real-world scenarios, the location of failures might be unknown or only partially known. In this work, we focus on cascading failures invo... View full abstract»

• ### Broadcast and Gossip Stochastic Average Consensus Algorithms in Directed Topologies

Publication Year: 2018, Page(s): 1
| | PDF (1274 KB)

We address the problem of a set of agents reaching consensus by computing the average of their initial states. We propose two randomized algorithms over a directed communication graph where either a random node broadcast its value or a randomly selected pair of nodes communicate in a distributed fashion. The proposed algorithms guarantee convergence in three important definitions, namely: almost s... View full abstract»

• ### Structural Oscillatority Analysis of Boolean Networks

Publication Year: 2018, Page(s): 1
| | PDF (2642 KB)

Boolean networks are system models whose binary-state nodes are interconnected. Although a number of studies have been conducted so far, it is usually assumed that the full information on the target system is available for analysis and design. This paper addresses a structural analysis problem for Boolean networks, i.e., the case when the information on the network structure is available but that ... View full abstract»

• ### Security Against Impersonation Attacks in Distributed Systems

Publication Year: 2018, Page(s): 1
| | PDF (1783 KB)

In a multi-agent system, transitioning from a centralized to a distributed decision-making strategy can introduce vulnerability to adversarial manipulation. We study the potential for adversarial manipulation in a class of graphical coordination games where the adversary can pose as a friendly agent in the game, thereby influencing the decision-making rules of a subset of agents. The adversary's i... View full abstract»

• ### Classification of the structurally controllable zero-patterns for driftless bilinear control systems

Publication Year: 2018, Page(s): 1
| | PDF (1039 KB)

We introduce and study the structural controllability of driftless bilinear control systems. We study two cases: in the first, the system matrices belong to one zero-pattern and in the second, the system matrices belong to one of several zeropatterns. We refer to them as the single and multiple patterns cases. In both cases, we prove that the structural controllability of driftless bilinear contro... View full abstract»

• ### A Microscopic Model for Lane-Less Traffic

Publication Year: 2018, Page(s): 1
| | PDF (2972 KB)

In this paper, a new model is introduced for traffic on broad roads, where the drivers do not follow lane-discipline. For both longitudinal and lateral motion, the driver reactions are assumed to be influenced by possibly a number of vehicles, obstacles and unmodelled entities in visibility cones to the front and to the sides of each vehicle. The network of influences and the resultant interaction... View full abstract»

• ### Cooperative Semiglobal Robust Output Regulation of Non-Introspective Nonlinear Agents with Partial Normal Form and State-Dependent High-Frequency Gain

Publication Year: 2018, Page(s): 1
| | PDF (2089 KB)

This paper investigates cooperative semiglobal robust output regulation problem for a class of non-introspective nonlinear multi-agent systems. Each agent of this class is allowed to have a partial normal form, instead of only the conventional normal form, with a state-dependent high-frequency gain. Besides, all agents are unaccessible to the controller states of their neighbors. In this setting, ... View full abstract»

• ### A Dual Splitting Approach for Distributed Resource Allocation with Regularization

Publication Year: 2018, Page(s): 1
| | PDF (1591 KB)

We deal with a class of distributed resource allocation problems where each agent attempts to minimize its own cost while respecting network-wide resource constraints as well as local capacity limits. This problem arises from many areas such as economic dispatch, network utility maximization and demand response. Most existing methods are centralized while few works are devoted to solving the probl... View full abstract»

• ### Robustness of synchronization to additive noise: how vulnerability depends on dynamics

Publication Year: 2018, Page(s): 1
| | PDF (551 KB)

From biological to technological networks, scientists and engineers must face the question of vulnerability to understand evolutionary processes or design resilient systems. Here, we examine the vulnerability of a network of coupled dynamical units to failure or malfunction of one of its nodes. More specifically, we study the effect of additive noise that is injected at one of the network sites on... View full abstract»

• ### Demand Shaping in Cellular Networks

Publication Year: 2018, Page(s): 1
| | PDF (1157 KB)

Demand shaping is a promising way to mitigate the wireless cellular capacity shortfall in the presence of ever-increasing wireless data demand. In this paper, we formulate demand shaping as an optimization problem that minimizes the variation in aggregate traffic. We design a distributed and randomized offline demand shaping algorithm under complete traffic information and prove its almost surely ... View full abstract»

• ### Structured decentralized control of positive systems with applications to combination drug therapy and leader selection in directed networks

Publication Year: 2018, Page(s): 1
| | PDF (2462 KB)

We study a class of structured optimal control problems in which the main diagonal of the dynamic matrix is a linear function of the design variable. While such problems are in general challenging and nonconvex, for positive systems we prove convexity of the $H_2$ and $H_infty$ optimal control formulations which allow for arbitrary convex...

• ### Attack-Resilient Pulse-Coupled Synchronization

Publication Year: 2018, Page(s): 1
| | PDF (484 KB)

Synchronization of pulse-coupled oscillators (PCOs) is gaining increased popularity in sensor networks and wireless communications due to its simplicity, implicit scalability, and high energy efficiency. However, most existing results are obtained in the absence of malicious attacks. This paper addresses pulsecoupled synchronization resilient to malicious attacks. Not only is the condition for ste...

• ### Adaptive Leader Following in Networks of Discrete-time Dynamical Systems: Algorithms and Global Convergence Analysis

Publication Year: 2018, Page(s): 1
| | PDF (314 KB)

Most of the results on adaptive leader following in multiagent systems pertain to continuous time agent dynamics. It is implicitly presumed that the information flow among agents is continuous and infinitely fast. Since in the discrete time setting there no need for this assumption, it is of interest to develop adaptive methods for leader-follower synchronization in networks of discrete-time dynam...

• ### Minimal Edge Addition for Network Controllability

Publication Year: 2018, Page(s): 1
| | PDF (2663 KB)

We address the problem of optimally modifying the topology of a directed dynamical network to ensure structural controllability. More precisely, given the structure of a directed dynamical network (i.e., an existing networked infrastructure), we propose a framework to find the minimum number of directed edges that need to be added to the network topology in order to render a structurally controlla...

• ### Distributed generalized Nash equilibria computation of monotone games via double-layer preconditioned proximal-point algorithms

Publication Year: 2018, Page(s): 1
| | PDF (837 KB)

In this paper, we investigate distributed generalized Nash equilibrium (GNE) computation of monotone games with affine coupling constraints. Each player can only utilize its local objective function, local feasible set and a local block of the coupling constraint, and can only communicate with its neighbours. We assume the game has monotone pseudo-subdifferential without Lipschitz continuity restr... View full abstract»

• ### On the Structural Perspective of Computational Effectiveness for Quantized Consensus in Layered UAV Networks

Publication Year: 2018, Page(s): 1
| | PDF (2920 KB)

Distributed computing tasks in small unmanned aerial vehicle (UAV) networks require effective data transmission schemes because of limited communication channels and transmission power. In this paper, we use decentralized consensus as a canonical distributed computing task to study the effectiveness of the data transmission in digitized (quantized) channels for UAV networks. We show that layered s... View full abstract»

• ### Robust global synchronization of Brockett oscillators

Publication Year: 2018, Page(s): 1
| | PDF (1292 KB)

In this article, motivated by a recent work of R. Brockett [1], a robust global synchronization problem of multistable Brockett oscillators has been studied within an Input-to-State Stability (ISS) framework. Two synchronization protocols are designed with respect to compact invariant sets of the unperturbed Brockett oscillator. The conditions obtained in our work are global and applicable to fami...
