• Single-Timescale Distributed GNE Seeking for Aggregative Games Over Networks via Forward-Backward Operator Splitting AI翻译
  作者：Gadjov, Dian; Pavel, Lacra
  作者单位：University of Toronto
  摘要：We consider aggregative games with affine coupling constraints, where agents have partial information on the aggregate value and can only communicate with neighboring agents. We propose a single-layer distributed algorithm that reaches a variational generalized Nash equilibrium, under constant step sizes. The algorithm works on a single timescale, i.e., it does not require multiple communication rounds between agents before updating their action. The convergence proof leverages an invariance p...
• Energy-Related Controllability of Signed Complex Networks With Laplacian Dynamics AI翻译

  摘要：This article investigates energy-related controllability of complex networks. Specifically, our objective is to establish controllability characteristics on signed complex networks, where the network units interact via neighbor-based Laplacian feedback and the network admits positive and negative edges to capture cooperative and competitive interactions among these units. The network units can be classified into leaders and followers. This article focuses on characterizing the energy-related c...
• Data-Driven Ambiguity Sets With Probabilistic Guarantees for Dynamic Processes AI翻译
  作者：Boskos, Dimitris; Cortes, Jorge; Martinez, Sonia

  摘要：Distributional ambiguity sets provide quantifiable ways to characterize the uncertainty about the true probability distribution of random variables of interest. This makes them a key element in data-driven robust optimization by exploiting high-confidence guarantees to hedge against uncertainty. This article explores the construction of Wasserstein ambiguity sets in dynamic scenarios, where data are collected progressively and may only reveal partial information about the unknown random variab...
• Consensus of Heterogeneous Second-Order Nonlinear Uncertain Multiagent Systems Under Switching Networks AI翻译
  作者：Lu, Maobin; Liu, Lu
  作者单位：Beijing Institute of Technology; City University of Hong Kong
  摘要：The consensus problem of heterogeneous second-order nonlinear uncertain multiagent systems under switching networks is addressed by a distributed control approach. The network communication of all systems is subject to arbitrarily bounded and nonuniform time-varying delays. Based on the internal model principle, a nonlinear distributed dynamic controller is developed to solve the problem. By means of Lyapunov analysis, consensus of heterogeneous second-order nonlinear multiagent systems is ach...
• Characterizing Energy-Related Controllability of Composite Complex Networks via Graph Product AI翻译

  摘要：This article characterizes the energy-related controllability of composite complex networks. We consider a class of composite networks constructed from simple factor networks via Cartesian product. The considered factor networks are leader-follower signed networks with neighbor-based Laplacian dynamics, adopting positive and negative edges to capture cooperative and competitive interactions among network units. Different from most existing works focusing on classical controllability, this arti...
• Local Optimality of Almost Piecewise-Linear Quantizers for Witsenhausen's Problem AI翻译
  作者：Ajorlou, Amir; Jadbabaie, Ali
  作者单位：Massachusetts Institute of Technology (MIT); Massachusetts Institute of Technology (MIT)
  摘要：We pose Witsenhausen's problem as a leader-follower game of incomplete information. The follower makes a noisy observation of the leader's action (who moves first) and chooses an action minimizing her expected deviation from the leader's action. Knowing this, the leader who observes the realization of the state chooses an action that minimizes her distance to the state of the world and the ex-ante expected deviation from the follower's action. We study the perfect Bayesian equilibria of the ga...
• Variable Selection According to Goodness of Fit in Nonparametric Nonlinear System Identification AI翻译
  作者：Cheng, Changming; Bai, Er-Wei
  作者单位：Shanghai Jiao Tong University; University of Iowa
  摘要：To achieve a parsimonious model, it is necessary to rank the importance of input variables according to some measures. The problem is nontrivial in the setting of nonlinear and nonparametric system identification. Difficulties lie in the lack of structural information of the unknown system, unknown underlying probabilistic distributions, and unknown nonlinear correlations of variables. In this article, we present a way to rank variables according to goodness of fit (GoF). Asymptotic results ar...
• Stability and Instability in Saddle Point Dynamics Part II: The Subgradient Method AI翻译
  作者：Holding, Thomas; Lestas, Ioannis
  作者单位：Imperial College London; University of Cambridge
  摘要：In part I we considered the problem of convergence to a saddle point of a concave-convex function in C-2 via gradient dynamics and an exact characterization was given to their asymptotic behavior. In part II we consider a general class of subgradient dynamics that provide a restriction in a convex domain. We show that despite the nonlinear and nonsmooth character of these dynamics their omega-limit set is comprised of solutions to only linear ODEs. In particular, we show that the latter are so...
• Robust Stabilization of a Class of Nonlinear Systems Controlled Over Communication Networks AI翻译

  摘要：The article deals with the stabilization of nonlinear systems in which the loop is closed over a lossy nonacknowledged communication network. Given a regional input-to-state (ISS) stabilizing state-feedback control law, designed without accounting for the network-induced delays, we propose a nonacknowledged communication policy that allows to deploy the above controller over the network without any modification, while preserving the regional ISS property. The time-varying delays and packet dro...
• Synthesis of Maximally Permissive Supervisors for Nondeterministic Discrete Event Systems With Nondeterministic Specifications AI翻译
  作者：Takai, Shigemasa
  作者单位：University of Osaka
  摘要：In this article, we consider the problem of synthesizing a nondeterministic supervisor for the plant and the specification modeled as nondeterministic automata. A similarity control problem requires us to synthesize a supervisor such that the supervised plant is simulated by the specification. Ideally, the synthesized supervisor should be as permissive as possible. We develop a method for synthesizing a maximally permissive supervisor that solves the similarity control problem.
