  摘要：In this article, we presented guaranteed independent and uniformmultivariable stabilitymargins for the H-infinity/LTR control, both in continuous and discrete time. In previous works, it was shown that the H-infinity/LTR control generalizes the linear quadratic Gaussian (LQG)/LTR setup, allowing the designer to better impose bounds on the complementary sensitivity frequency peak in the loop-shaping procedure. In this article, we extend this result by showing that H-infinity/LTR control is able...
• Existence of Team-Optimal Strategies in Teams With Countable Observation Spaces AI翻译

  摘要：Team problems, in which multiple agents act to minimize a common expected cost function, are generally intractable. The problem of establishing the existence of team-optimal strategies has received significant attention in the past decade. In this article, we present a proof of the existence of team-optimal strategies in a class of teams in which observations are realized in a countable set and are shared among the agents and the action sets are noncompact. We derive sufficient conditions unde...
• State Estimation of Kermack-McKendrick PDE Model With Latent Period and Observation Delay AI翻译

  摘要：In this article, we study the problem of estimating the state of the linearized Kermack-McKendrick partial differential equation (PDE) model in real time. Especially, we assume that the model contains two kinds of delays. One of them is contained in the nonlocal boundary condition, which expresses the latent period of infection. The other is an observation delay, which corresponds to the time needed for counting the number of infected people at an infection elapsed time. The element of time la...
• Structural Robustness to Noise in Consensus Networks: Impact of Degrees and Distances, Fundamental Limits, and Extremal Graphs AI翻译

  摘要：We investigate how the graph topology influences the robustness to noise in undirected linear consensus networks. We measure the structural robustness by using the smallest possible value of steady-state population variance of states under the noisy consensus dynamics with edge weights from the unit interval. We derive tight upper and lower bounds on the structural robustness of networks based on the average distance between nodes and the average node degree. Using the proposed bounds, we char...
• Distributed Bandit Online Convex Optimization With Time-Varying Coupled Inequality Constraints AI翻译

  摘要：Distributed bandit online convex optimization with time-varying coupled inequality constraints is considered, motivated by a repeated game between a group of learners and an adversary. The learners attempt tominimize a sequence of global loss functions and at the same time satisfy a sequence of coupled constraint functions, where the constraints are coupled across the distributed learners at each round. The global loss and the coupled constraint functions are the sum of local convex loss and c...
• Compensation of Spatially Varying Input Delay in Distributed Control of Reaction-Diffusion PDEs AI翻译

  摘要：We develop a predictor-based distributed feedback controller that guarantees exponential stability for a class of reaction-diffusion partial differential equations (PDEs) subject to spatially varying input delay. The delay depends on the location of the input in the spatial domain. In order to design a distributed controller to compensate the spatially varying delay, we first introduce an implicit backstepping transformation, which contains the state of the target system on both sides of the d...
• Distributed Online Optimization for Multi-Agent Networks With Coupled Inequality Constraints AI翻译
  作者：Li, Xiuxian; Yi, Xinlei; Xie, Lihua
  作者单位：Nanyang Technological University; Royal Institute of Technology
  摘要：This article investigates the distributed online optimization problem over a multi-agent network subject to local set constraints and coupled inequality constraints, which has a lot of applications in many areas, such as wireless sensor networks, power systems, and plug-in electric vehicles. In this problem, the cost function at each time step is the sum of local cost functions with each of them being gradually revealed to its corresponding agent, and meanwhile only local functions in coupled ...
• On Constructive Extractability of Measurable Selectors of Set-Valued Maps AI翻译
  作者：Osinenko, Pavel; Streif, Stefan
  作者单位：Skolkovo Institute of Science & Technology; Technische Universitat Chemnitz
  摘要：This article investigates the possibility of constructive extraction of measurable selector from set-valued maps, which may commonly arise in viability theory, optimal control, discontinuous systems, etc. For instance, existence of solutions to certain differential inclusions often requires iterative extraction of measurable selectors. Next, optimal controls are in general nonunique which naturally leads to an optimal set-valued function. Finally, a viable control law can be seen, in general, ...
• Wasserstein Distributionally Robust Stochastic Control: A Data-Driven Approach AI翻译
  作者：Yang, Insoon

  摘要：Standard stochastic control methods assume that the probability distribution of uncertain variables is available. Unfortunately, in practice, obtaining accurate distribution information is a challenging task. To resolve this issue, in this article we investigate the problem of designing a control policy that is robust against errors in the empirical distribution obtained from data. This problem can be formulated as a two-player zero-sum dynamic game problem, where the action space of the adver...
• Global Stabilization by Memoryless Feedback for Nonlinear Systems With a Limited Input Delay and Large State Delays AI翻译
  作者：Zhao, Congran; Lin, Wei
  作者单位：Jiangsu University; University System of Ohio; Case Western Reserve University
  摘要：This article studies the problem of global asymptotic stabilization (GAS) by memoryless state and/or output feedback for a family of nonlinear systems with delays in the state and input. Under a linear growth condition, together with the lower-triangular bounding requirement, it is proved that GAS of the time-delay nonlinear system under consideration is achievable by memoryless state and output feedback, respectively, as long as the input delay is limited. With the aid of the Lyapunov-Krasovs...
