  摘要：The synchronization problem of complex dynamical networks with impulsive effects has been extensively addressed. However, great challenges arise when applying the existing synchronization criteria to networks with uncertain impulses. In this article, we investigate the adaptive synchronization problem of complex networks with uncertain impulses. First, the adaptive control gain is proved to be bounded for both synchronizing and desynchronizing impulses. Then, adaptive synchronization criteria ...
• Prescribed Time Consensus Control of Multiagent Systems With Minimized Time-Varying Cost Function AI翻译

  摘要：In this note, a fully distributed and prescribed-time control approach is developed to achieve consensus for multiple agent systems under certain optimal constraints. By virtue of local gradient information, a new estimator is first constructed to acquire global gradient information. Based on the well-known result on fixed-time control, a novel prescribed time lemma is derived by specifying certain design parameters properly, with which the three objectives, consensus, estimation, and optimiza...
• Dual Seminorms, Ergodic Coefficients and Semicontraction Theory AI翻译

  摘要：Dynamical systems that are contracting on a subspace are said to be semicontracting. Semicontraction theory is a useful tool in the study of consensus algorithms and dynamical flow systems such as Markov chains. To develop a comprehensive theory of semicontracting systems, we investigate seminorms on vector spaces and define two canonical notions: Projection and distance seminorms. We show that the well-known l(p) ergodic coefficients are induced matrix seminorms and play a central role in sta...
• Policy Optimization Over Submanifolds for Linearly Constrained Feedback Synthesis AI翻译

  摘要：In this article, we study linearly constrained policy optimization over the manifold of Schur stabilizing controllers, equipped with a Riemannian metric that emerges naturally in the context of optimal control problems. We provide extrinsic analysis of a generic constrained smooth cost function that subsequently facilitates subsuming any such constrained problem into this framework. By studying the second-order geometry of this manifold, we provide a Newton-type algorithm that does not rely on...
• Small-Gain and Small-Angle Conditions for Feedback Stability Analysis of Linear Stochastic Systems AI翻译

  摘要：In this article, we formulate feedback control problems involving stochastic systems and stochastic signals and obtain stability conditions based on the notions called gains and angles. The family of systems under investigation is represented by a discrete-time linear time-varying stochastic (LTVS) model, which generalizes the intensively studied multiplicative stochastic model. Such formulation may incorporate widely encountered networked control problems involving fading and packet-drop comm...
• Observer-Based Asynchronous Control for Stochastic Nonhomogeneous Semi-Markov Jump Systems AI翻译
  作者：Wang, Dong; Wu, Feiyue; Lian, Jie; Li, Siyi

  摘要：This article investigates the stabilization of a class of stochastic nonhomogeneous semi-Markov jump systems (SNSMJSs). As a result of incomplete access to the system's state and the occurrence of asynchronous phenomena that occur during information transmission, the control design of the SNSMJSs becomes significantly more complicated. To tackle such a challenge, an observer-based asynchronous controller embedded with a hidden Markov model is proposed. First, an algebraic relationship among tr...
• Lyapunov-Type Criteria of Absorbing Continuous-Time Markov Chains AI翻译

  摘要：The Lyapunov stability theory is developed for absorbing continuous-time Markov chains (CT-MCs) in this technical note. The derived stability criteria are all necessary and sufficient for absorbing CT-MCs and set absorbing CT-MCs, where Lyapunov functions can be constructed in a polynomial amount of time with respect to the cardinality of state spaces. Furthermore, the gap between Lyapunov functions of the CT-MCs and of the discrete-time Markov chains is bridged by the feature that the length ...
• Specified-Time Affine Formation Maneuver Control of Multiagent Systems Over Directed Networks AI翻译

  摘要：In this article, the specified-time affine formation maneuver control (AFMC) problem is studied with a leader-follower structure over a directed communication network. First, by means of Pontraygin's maximum principle and motion-planning techniques, a specified-time AFMC algorithm is designed for the second-integrator systems with dynamic leaders, which can lead the followers to achieve the desired affine formation at a specified settling time according to mission requirements and environmenta...
• Cooperative Multiagent Reinforcement Learning With Partial Observations AI翻译
  作者：Zhang, Yan; Zavlanos, Michael M.
  作者单位：Duke University
  摘要：In this article, we propose a distributed zeroth-order policy optimization method for multiagent reinforcement learning (MARL). Existing MARL algorithms often assume that every agent can observe the states and actions of all the other agents in the network. This can be impractical in large-scale problems, where sharing the state and action information with multihop neighbors may incur significant communication overhead. The advantage of the proposed zeroth-order policy optimization method is t...
• A Kernel-Based Approach to Errors-in-Variables Identification of Stable Multivariable Linear Systems AI翻译

  摘要：In this article, we present a kernel-based nonparametric approach to identifying stable multi-input multioutput (MIMO) linear systems in the presence of bounded noise affecting both the input and the output measurements. First, we formulate the considered problem in terms of robust optimization techniques. Then, we show that the formulated robust optimization problem can be solved using semidefinite optimization. Since the involved optimization problem is computationally demanding, we also pro...
