  摘要：This article focuses on open multiagent systems (OMAS), where agents can dynamically join and leave the network. The primary objective is to achieve a property termed nondisruptive consensus (NDC), which ensures that the state evolution of existing agents remains unaffected by newly joined agents. To address this, we introduce the notions of joint robustness and limited openness, which are shown to be critical for maintaining system stability under dynamic agent participation. Leveraging these...

  摘要：Coordinating communication and control is a key component in the stability and performance of networked multiagent systems. While single user networked control systems have gained a lot of attention within this domain, in this work, we address the more challenging problem of large population multiteam dynamic games. In particular, each team constitutes two decision-makers (namely, the sensor and the controller) who coordinate over a shared network to control a dynamically evolving state of int...

  摘要：This article proposes a novel distributed nonconvex stochastic optimization algorithm that can achieve privacy protection and convergence simultaneously while improving communication efficiency. Specifically, each node adds general privacy noises to its local state to avoid information leakage, and then, quantizes its noise-perturbed state before transmitting to improve communication efficiency. By using a sampling parameter-controlled subsampling method, the proposed algorithm enhances the di...
• User Preferences-Based Incompatible Multiobjective Iterative Learning Tracking Control AI翻译

  摘要：In multisensor systems, the output of each sensor is typically required to track a reference within a specified time frame. This situation exemplifies a multiobjective tracking problem (MOTP). By nature, MOTP involves multiple conflicting optimization objectives, precluding us from finding a single optimal solution. Instead, a set of solutions known as Pareto optimal solutions (POSs) exists, representing various tradeoffs among the objectives. In practice, the goal is typically to identify an ...

  摘要：In this article, the leader-following consensus problem of randomly sampled multiagent systems (MASs) subject to energy-dependent packet dropouts is investigated. Leveraging a hold-input strategy, we first establish a unified discrete-time framework that simultaneously accounts for the impacts of noisy sampling intervals and energy-dependent packet dropouts. Under the centralized energy allocation scheme, we provide a method to calculate the probability of successful sampled-data transmission ...
• Innovation-Based Stealthy Attacks on Remote State Estimators Using the Wasserstein Distance AI翻译

  摘要：We study the problem of designing an attacking strategy for a remote state estimator of a linear Gaussian cyber-physical system. We focus on an innovation-based attack on a scenario, in which a smart sensor transmits innovations via a wireless communication network. We start by considering the attacking scheme in its most general form, and constrain its design so that it remains stealthy to the attack detector at the receiver side. To this end, we consider two stealthiness constraints. First, ...
• Enforcement of Time-Constrained GMECs on Time-Colored Petri Nets AI翻译
  作者：Dong, Yifan; Lefebvre, Dimitri; Li, Zhiwu

  摘要：This article addresses the enforcement of a class of generalized mutual exclusion constraints (GMECs) within time constraints on time-colored Petri nets by adjusting the time restrictions of transitions with soft time intervals. Colored GMECs are defined to represent a set of markings that are determined by a subset of colors. Then, time constraints are imposed on the proposed colored GMECs to further refine the representation of state specifications in real-time systems. To enhance the modeli...
• Identification of Periodic Sensor-Reading Modification Attacks in Cyber-Physical Systems AI翻译

  摘要：Cyber-physical systems (CPSs) are extensively utilized in industry and critical infrastructures due to their ability to facilitate mutual cooperation and interaction between physical and virtual worlds. Nevertheless, their security has been increasingly threatened by cyber attacks. Motivated by the need to address the resulting security concerns, this work studies a class of periodic sensor attacks that periodically modify sensor-readings to disrupt the performance of remote estimators in a sy...

  摘要：Robust control in multiagent systems (MASs), understood as the ability to solve a cooperative distributed task despite uncertainties and disturbances in the agents' dynamics or the shared networking environment, is a crucial aspect of the practical applicability of the MAS paradigm. In this work, novel control mechanisms involving adaptation and cooperation are proposed to enhance the robust performance of MASs. A comprehensive case study is presented to illustrate the potential of the propose...

  摘要：Subspace identification methods (SIMs) are known for their simple parameterization for MIMO systems and robust numerical properties. However, a comprehensive statistical analysis of SIMs remains an open problem. Following a three-step procedure generally used in SIMs, this work presents a finite sample analysis for open-loop SIMs. In Step 1, we begin with a parsimonious SIM. Leveraging a recent analysis of an individual ARX model, we obtain a union error bound for a Hankel-like matrix construc...
