  摘要：Recent work (Rantzer, 2022) formulated a class of optimal control problems involving positive linear systems, linear stage costs, and elementwise constraints on control. It was shown that the problem admits linear optimal cost and the associated Bellman's equation can be characterized by a finite-dimensional nonlinear equation, which is solved by linear programming. In this work, we report exact dynamic programming (DP) theories for the same class of problems. Moreover, we extend the results t...

  摘要：This article is concerned with the problem of distributed Kalman filtering over sensor networks under two-bitrate periodic coding strategies. Initially, the optimal estimates for sensor individuals are acquired using the conventional Kalman filter. Subsequently, the information pair, consisting of the local estimate and the corresponding covariance, is exchanged among their immediate neighbors to achieve cooperative estimation. Due to the constrained network bandwidth, a vector/matrix quantiza...
• Online Distributed Algorithms for Online Noncooperative Games With Stochastic Cost Functions: High Probability Bound of Regrets AI翻译

  摘要：In this article, online noncooperative games without full decision information are studied, where the goal of players is to seek the Nash equilibria in a distributed manner. Different from the existing works on online noncooperative games, here we consider the case where the cost functions are stochastic. In the problem, each player only has access to a noisy gradient of its own cost function and a local action set, and needs to make decisions before the current noisy gradient information is r...

  摘要：This article considers the problem of the bearing-based formation control with disturbance rejection for a group of agents under the leader-follower structure. The disturbances are in the form of trigonometric polynomials with arbitrary unknown amplitudes, unknown initial phases, and known or unknown frequencies. For the case of the known frequencies, we employ the canonical internal model to solve the problem, and, for the case of the unknown frequencies, we combine the canonical internal mod...

  摘要：We propose a method for analyzing the distributed random coordinate descent algorithm for solving separable resource allocation problems in the context of an open multiagent system, where agents can be replaced during the process. In particular, we characterize the evolution of the distance to the minimizer in expectation by following a time-varying optimization approach which builds on two components. First, we establish the linear convergence of the algorithm in closed systems, in terms of t...
• Estimation and Prevention of Actuator Enablement Attacks in Discrete-Event Systems Under Supervisory Control AI翻译
  作者：He, Zhaoyang; Wu, Naiqi; Li, Zhiwu
  作者单位：Macau University of Science & Technology; Xidian University
  摘要：This article addresses the problems of estimation and prevention of actuator attacks in the framework of discrete-event systems under supervisory control, where an attack estimation helps an intruder evaluate whether a controlled system can be driven to an undesirable state after being attacked based on partial observation before an actual attack is enforced. The intruder implements an actuator enablement attack by enabling a vulnerable actuator event that has been disabled by a supervisor. To...
• Boosting One-Point Derivative-Free Online Optimization via Residual Feedback AI翻译

  摘要：Zeroth-order optimization (ZO) typically relies on two-point feedback to estimate the gradient of the objective function. Nevertheless, two-point feedback cannot be used for online optimization with time-varying objective functions, where only a single query of the function value is possible at each time step. In this work, we propose a new one-point feedback method for online optimization that estimates the gradient using the residual between two feedback points at consecutive time instants. ...
• Rejection of Sinusoidal Disturbances With Unknown Slowly Time-Varying Frequencies for Linear Time-Invariant Systems AI翻译
  作者：Stewart, Jacob; Ioannou, Petros
  作者单位：University of Southern California
  摘要：In recent years, adaptive schemes have been developed to reject sinusoidal disturbances with unknown frequencies, phases, and amplitudes. However, the analysis methods typically used are only suitable for sinusoidal disturbances with piecewise constant frequencies, ignoring smooth continuous variations. This note proposes a robust adaptive scheme to reject output disturbances dominated by sinusoidal terms with unknown time-varying frequencies. The performance is first analyzed in the ideal cas...
• Synthesis of Distributed Covert Sensor-Actuator Attackers AI翻译
  作者：Tai, Ruochen; Lin, Liyong; Zhu, Yuting; Su, Rong
  作者单位：Nanyang Technological University
  摘要：This article investigates the synthesis of distributed attackers for distributed discrete-event systems, where the distributed attackers could implement sensor insertion/deletion/replacement attacks and actuator enablement/disablement attacks. The distributed attackers to be synthesized should fulfill the following goals: 1) Each local sensor-actuator attacker needs to remain covert against all the distributed monitors, which are used to detect the existence of attacks; and 2) the distributed ...
• A Unified Framework for Verification of Observational Properties for Partially-Observed Discrete-Event Systems AI翻译
  作者：Zhao, Jianing; Li, Shaoyuan; Yin, Xiang
  作者单位：Shanghai Jiao Tong University
  摘要：In this article, we investigate property verification problems in partially-observed discrete-event systems (DES). Particularly, we are interested in verifying observational properties that are related to the information-flow of the system. Observational properties considered here include diagnosability, predictability, detectability, and opacity, which have drawn considerable attentions in the literature. However, in contrast to existing results, where different verification procedures are de...
