  摘要：While for coupled hyperbolic partial differential equations (PDEs) of first order, there now exist numerous PDE backstepping designs, systems with zero speed, i.e., without convection but involving infinite-dimensional ordinary differential equations (ODEs), which arise in many applications, from environmental engineering to lasers to manufacturing, have received virtually no attention. In this article, we introduce single-input boundary feedback designs for a linear 1-D hyperbolic system with...

  摘要：How to realize high-level autonomy of individuals is one of the key technical issues to promote swarm intelligence of multiagent (node) systems with collective tasks, while the fully distributed design is a potential way to achieve this goal. This article works on the fully distributed state estimation and cooperative stabilization problem of linear time-invariant (LTI) plants with multiple nodes communicating over general directed graphs, and is aimed to provide a fully distributed framework ...
• Event Concealment and Concealability Enforcement in Discrete Event Systems Under Partial Observation AI翻译

  摘要：In this article, we investigate event concealment and concealability enforcement in discrete event systems modeled as nondeterministic finite automata under partial observation. Given a subset of secret events in a given system, concealability holds if the occurrences of all secret events remain hidden to a curious observer (an eavesdropper). When concealability of a system does not hold, we analyze how a defensive function, placed at the interface of the system with the eavesdropper, can be u...
• No-Regret Distributed Learning in Subnetwork Zero-Sum Games AI翻译

  摘要：In this article, we consider a distributed learning problem in a subnetwork zero-sum game, where agents are competing in different subnetworks. These agents are connected through time-varying graphs where each agent has its own cost function and can receive information from its neighbors. We propose a distributed mirror descent algorithm for computing a Nash equilibrium and establish a sublinear regret bound on the sequence of iterates when the graphs are uniformly strongly connected and the c...
• Stability Analysis of Block Logical Dynamical Systems and Its Application in Logical Networks With Time Delay AI翻译
  作者：Li, Haitao; Li, Yalu; Li, Wenrong; Liu, Yansheng
  作者单位：Shandong Normal University; Qingdao University
  摘要：A new class of nonlinear systems, block logical dynamical systems (BLDSs), is introduced in this note. The existence and uniqueness of solution to BLDSs are first investigated. Then, the topological structure and global stability of BLDSs are analyzed, and a novel criterion is presented to verify the global stability of BLDSs. Finally, the stability of BLDSs is used to study the stability of logical networks subject to time delay. It is shown that the introduction of BLDSs can considerably red...
• Semi-Global and Robust Finite-Time Regulation of the Heisenberg System AI翻译
  作者：Mera, Manuel; Rios, Hector
  作者单位：Instituto Politecnico Nacional - Mexico
  摘要：In this article, a novel controller design is proposed to solve the finite-time regulation problem of the Heisenberg system, a prototypical nonholonomic system diffeomorphic to the Brockett integrator and many physical systems. Some inherent properties of the Heisenberg system, e.g., the skew-symmetric/diagonal structure, are exploited to obtain a simple-to-tune and bounded control that ensures the finite-time convergence to any point of the state space outside of a zero-measure set. In additi...

  摘要：In this work, we consider the problem of event-triggered implementation of control laws designed for the local stabilization of nonlinear systems with center manifolds. We propose event-triggering conditions which are derived from a local input-to-state stability characterization of such systems. The triggering conditions ensure local ultimate boundedness of the trajectories and the existence of a uniform positive lower bound for the inter-event times. The ultimate bound can be made arbitraril...
• Disturbance Estimator-Based Boundary Control for a Chaotic Wave System With Disturbance AI翻译

  作者单位：Foshan University; Yeungnam University; Central South University; Chinese Academy of Sciences; Academy of Mathematics & System Sciences, CAS; North China Electric Power University
  摘要：In this article, boundary output feedback exponential stabilization and disturbance rejection for a chaotic wave system with superlinear boundary condition and unknown boundary disturbance are investigated. By using measured outputs, an infinite-dimensional disturbance estimator is designed to estimate the unknown boundary disturbance without requiring the conventional boundedness of its derivative and high gain of the estimator. A novel disturbance estimator-based boundary control, comprised ...
• On Input Delay Tolerance of Stochastic Nonlinear Systems With Dominant Homogeneity of Degree Zero AI翻译
  作者：Yu, Xin; Lin, Wei
  作者单位：Jiangsu Normal University; University System of Ohio; Case Western Reserve University
  摘要：This article investigates the problem of when stochastic nonlinear systems that are $l$th moment asymptotically stabilizable ($l$th MAS) are tolerant to input delay. Substantially different from the existing related literature, our focal point is on a class of stochastic systems that may be neither locally Lipschitz continuous nor linear growth, and not $l$th MAS by smooth feedback. To address the problem of input delay tolerance (IDT), we first present the existence of the solutions for a cla...
• Probabilistic Constraint for Safety-Critical Reinforcement Learning AI翻译

  摘要：In this article, we consider the problem of learning safe policies for probabilistic-constrained reinforcement learning (RL). Specifically, a safe policy or controller is one that, with high probability, maintains the trajectory of the agent in a given safe set. We establish a connection between this probabilistic-constrained setting and the cumulative-constrained formulation that is frequently explored in the existing literature. We provide theoretical bounds elucidating that the probabilisti...
