  摘要：In this article, we investigate the synthesis problem of edit functions for opacity enforcement in systems modeled as partially observed finite-state automata. For better plausible deniability for the edit functions, in cases where the intruder may learn/know their existence, a synthesis problem for nondeterministic edit functions under a publicly known setting was introduced in the literature, but not yet fully solved. In light of this, we revisit the publicly known edit mechanism by proposin...
• Leader-Follower Density Control of Spatial Dynamics in Large-Scale Multiagent Systems AI翻译

  摘要：We address the problem of controlling the density of a large ensemble of follower agents by acting on a group of leader agents that interact with them. Using coupled partial integro-differential equations to describe leader and follower density dynamics, we establish feasibility conditions and develop two control architectures ensuring global stability. The first employs feedforward control on the followers' and a feedback on the leaders' density. The second implements a dual feedback loop thr...

  摘要：In this article, we investigate a distributed generalized Nash equilibrium (GNE) seeking problem for multicluster games, where each cluster consists of multiple players. Different from most of the existing multicluster game studies, the multicluster games considered nonconvex cost functions, nonconvex (coupled) inequality constraints, and nonaffine (coupled) equality constraints. Each player in a cluster communicates and cooperates with other players based on a directed connected network to ma...
• A Stealthy False Data Injection Attack Scheme Against Sensor Measurements Using Partial System Knowledge AI翻译

  摘要：Attack design is indispensable for analyzing potential risks of networked control systems (NCSs). However, the remote control center is usually well protected and its knowledge is difficult to be disclosed, which becomes a major obstacle in developing stealthy false data injection (FDI) attack scheme because only partial system knowledge (i.e., the system matrices of the physical plant) could be used. To meet this challenge, a novel stealthy FDI attack scheme against the sensor measurement is ...
• Distributed Strategy Design for Free-In and Free-Out Aggregative Games AI翻译

  摘要：This article proposes a new aggregative game model over free-in and free-out networks, in which each player can freely join and leave the network at its timing and aims to minimize its total cost during its active period. To enable the players to make self-beneficial decisions in such a dynamic environment, it is assumed that the players can locally store and exchange the historical action information. Based on the stored information, a distributed strategy is established, in which each player...
• Duality Between Controllability and Observability for Target Control and Estimation in Networks AI翻译
  作者：Montanari, Arthur N.; Duan, Chao; Motter, Adilson E.

  摘要：Output controllability and functional observability are properties that enable, respectively, the control and estimation of part of the state vector. These notions are of utmost importance in applications to high-dimensional systems, such as large-scale networks, in which only a target subset of variables (nodes) is sought to be controlled or estimated. Although the duality between full-state controllability and observability is well established, the characterization of the duality between the...
• A Continuous-Time Violation-Free Multiagent Optimization Algorithm and Its Applications to Safe Distributed Control AI翻译
  作者：Tan, Xiao; Liu, Changxin; Johansson, Karl H.; Dimarogonas, Dimos V.
  作者单位：Royal Institute of Technology
  摘要：In this work, we propose a continuous-time distributed optimization algorithm with guaranteed zero coupling constraint violation and apply it to safe distributed control in the presence of multiple control barrier functions (CBFs). The optimization problem is defined over a network that collectively minimizes a separable cost function with coupled linear constraints. An equivalent optimization problem with auxiliary decision variables and a decoupling structure is proposed. A sensitivity analy...
• Properties of Fundamental Matrix Groups for High-Order Linear Time-Invariant Systems AI翻译
  作者：Wu, Ai-Guo
  作者单位：Harbin Institute of Technology
  摘要：In this article, commutativity-like relations between the fundamental matrix groups and the system matrices are established for high-order continuous-time and discrete-time linear time-invariant systems. With the aid of the commutativity-like properties, alternative proofs of the formulae for state responses are provided for these two classes of high-order linear time-invariant systems.
• Sensor and Filter Attacks Against Distributed State Estimation With Dual Stealthiness AI翻译
  作者：Jin, Kaijing; Ye, Dan
  作者单位：Northeastern University - China; Northeastern University - China
  摘要：To reveal the security vulnerabilities of distributed estimation systems, we investigate the existence of false data injection attacks in this article, where attacks can corrupt sensor data and filter data. Considering the innovation-based and consensus-based strict stealthiness, a successful attack should ensure the divergence of each local estimation and not affect innovation and consensus signals. By analyzing the null space of system matrices, the necessary and sufficient conditions for th...
• Discrete-Time Partially Observable Stochastic Optimal Control Problems of McKean-Vlasov Type and Branching Particle System Approximations AI翻译
  作者：Wan, Hexiang; Wang, Guangchen; Xiong, Jie

  摘要：This article investigates a broad category of McKean-Vlasov type discrete-time partially observable stochastic optimal control problems. The first goal is to prove the dynamic programming principle (DPP) by means of the measurable selection argument, which provides a methodology for finding both the value function as well as the optimal control. Here, we employ the Nisio semigroup technology, which is an intrinsic characterization of the DPP. Then, we derive the recursive formula for the filte...
