  摘要：We propose a new distributed optimization algorithm for solving a class of constrained optimization problems in which the objective function is separable (i.e., the sum of local objective functions of agents), the optimization variables of distributed agents, which are subject to nontrivial local constraints, are coupled by global constraints, and only noisy observations are available to estimate (the gradients of) local objective functions. In many practical scenarios, agents may not be willi...

  摘要：Adversarial attacks during training can strongly influence the performance of multiagent reinforcement learning algorithms. It is, thus, highly desirable to augment existing algorithms such that the impact of adversarial attacks on cooperative networks is at least bounded. We consider a fully decentralized network, where each agent receives a local reward and observes the global state and action. We propose a resilient consensus-based actor-critic algorithm, whereby each agent estimates the te...
• Collisions-Free Distributed Cooperative Output Regulation of Nonlinear Multiagent Systems AI翻译
  作者：An, Liwei; Yang, Guang-Hong

  摘要：This article studies the problem of collision/obstacle avoidance in the distributed cooperative output regulation of nonlinear multiagent systems (MASs). First, a nonlinear distributed command governor equipped by two dynamical barrier functions is constructed to generate safe command signals. Then, a filtering-based distributed command tracking control scheme is proposed. It is shown that the MAS adaptively reconfigures its formation shape in a distributed way when entering into the barrier f...
• Cooperative Output Regulation for Continuous-Time Linear Periodic Systems AI翻译

  摘要：This note investigates the cooperative output regulation problem for linear periodically time-varying systems. The problem is divided into two subproblems: solving periodic differential Sylvester equations (PDSEs) and designing a suitable time-varying distributed controller to stabilize an augmented multiagent system. First, the solvability of the PDSEs is discussed under an observability condition. Then, a dynamic output-feedback controller based on the internal model principle is proposed, w...
• Performance Bounds for Quantum Feedback Control AI翻译

  摘要：The limits of quantum feedback control have immediate consequences for quantum information science at large, yet remain largely unexplored. Here, we combine quantum filtering theory and moment-sum-of-squares techniques to construct a hierarchy of convex optimization problems that furnish monotonically improving, computable bounds on the best attainable performance for a broad class of quantum feedback control problems. These bounds may serve as witnesses of fundamental limitations, optimality ...
• Robust Feedback Instability Analysis in the L2-Gap AI翻译
  作者：Khong, Sei Zhen; Cantoni, Michael; Hara, Shinji; Kao, Chung-Yao

  摘要：The robustness of instability is investigated for feedback interconnections of rational transfer functions, motivated by the relevance of such in the study of oscillatory dynamics. An analysis is presented in terms of normalized coprime factorizations and the L-2-gap metric. The main result is a necessary and sufficient condition for feedback instability to persist across a particular uncertainty set for one open-loop component of the interconnection, with the other component fixed. This uncer...

  摘要：This article contributes a Lyapunov formulation for prescribed performance controller designs. In particular, we first show that the closed-loop system of a typical class of prescribed performance control systems can be transformed into an interconnection of input-to-state practically stable (ISpS) subsystems characterized by ISpS-Lyapunov functions. Then, we take advantage of the gain-interconnections between the subsystems and construct a Lyapunov function for the closed-loop system. The pro...
• Convergence in Nonlinear Optimal Sampled-Data Control Problems AI翻译

  摘要：Consider, on the one part, a general nonlinear finite- dimensional optimal control problem and assume that it has a unique solution x*. On the other part, consider the sampled-data control version of it. Under appropriate assumptions, we prove that the optimal state of the sampled-data problem converges uniformly to x* as the norm of the partition tends to zero. Moreover, applying the Pontryagin maximum principle (PMP) to both problems, we prove that, if x* has a unique weak extremal lift with...
• Synthesis of Input-to-State Attractivity Controllers for Transition Systems With Disturbances AI翻译
  作者：Apaza-Perez, W. Alejandro; Girard, Antoine
  作者单位：Universite Paris Saclay; Centre National de la Recherche Scientifique (CNRS)
  摘要：In this article, we introduce the notion of input-to-state attractivity (ISA) controllers for a class of finite transition systems with disturbances. The performances of an ISA controller are characterized by a gain function that quantifies the deviation of closed-loop trajectories from the target set as a function of the amplitude of past disturbances on a bounded time window. We prove the existence of controllers that are gain-optimal (GO) in the sense that their gain function is minimal (wi...
• Finite Lyapunov Stability Test for a Class of Linear Systems With Pointwise and Distributed Delays AI翻译

  摘要：This contribution presents two exponential stability criteria (necessary and sufficient conditions) for linear systems with multiple pointwise and distributed delays. An important property is that the stability test requires a finite number of mathematical operations. The results are given in terms of the delay Lyapunov matrix and the fundamental matrix of the system. The exact construction of these matrices is possible for systems with delays multiple of a basic one and distributed delays wit...
