  摘要：The estimation of a mixture of real-and integer-valued parameter vectors appears in different control and signal processing applications. In some particular cases, for instance when dealing with covariance or rotation matrices, the real parameter must be constrained by geometrical properties. This article considers the general estimation problem containing both Lie group and integer parameters, for which the corresponding performance bound is a important missing tool. Leveraging recent results...
• A Novel Exponential Stability Result for Impulsive Systems With Estimation of the Attraction Domain AI翻译

  摘要：This article is concerned with the stability problem of impulsive systems in Lyapunov framework. Different from the traditional stability results, a class of discrete dynamic decomposition methods is introduced in this article, whose key advantage is that it describes the impulsive action by breaking it into different types. It is particularly helpful when the original problem involves complicated impulsive actions, especially for some nonlinear impulses. Based on such method, we propose a nov...

  摘要：This article proposes a data-driven estimation and control co-design method for a class of unknown linear network control systems (NCSs) under denial-of-service (DoS) and false data injection (FDI) attacks simultaneously. First, a new piecewise observer is designed to provide the real-time estimates of the unavailable system state and the unknown FDI attack signal in the presence of DoS attacks. Under the assumption that the system matrices of the considered NCSs are known in advance, model-ba...
• Chance-Constrained Dynamic Encoding-Based Control Over Noisy Communication Channels: An Active Bit-Flip-Error-Resistant Approach AI翻译
  作者：Zhu, Kaiqun; Wang, Zidong; Ding, Derui; Li, Zhenning; Xu, Cheng-Zhong

  摘要：This article investigates the chance-constrained control problem for uncertain systems, with a focus on the distortion of signal transmission between the controller and the actuator caused by noisy and bandwidth-limited communication channels, and its impact on the system's control performance. Initially, a binary dynamic encoding mechanism (DEM) is employed to encode the system's amplitude-continuous signal into a finite-length binary string, aiming to mitigate the communication burden. In th...
• Optimal Set-Membership Smoothing AI翻译

  摘要：This article studies the optimal set-membership smoothing (SMSing) problem for the system with bounded noises. By adopting the mathematical concept of uncertain variables, an optimal SMSing framework is established for the first time. This optimal framework reveals the principles of SMSing and the relationship between set-membership filtering and smoothing. Based on the design principles, we put forward two SMSing algorithms: one for linear systems with zonotopic constrained uncertainties, whe...
• A Model Reduction Approach for Discrete-Time Coupled Systems With Input Delays via Bivariate Fundamental Matrices AI翻译
  作者：Wu, Ai-Guo; Shen, Shi-Long; Zhang, Jie; Mei, Jie
  作者单位：Harbin Institute of Technology; Southern University of Science & Technology
  摘要：In this article, the model reduction approach is investigated for discrete-time linear coupled systems with input delays. For this purpose, a new class of fundamental matrices is presented for state response analysis of this kind of systems. In order to characterize the effect of all initial values, this new fundamental matrix is defined in terms of two independent variables, and thus is called the bivariate fundamental matrix. Besides, some interesting properties of bivariate fundamental matr...
• Inverse Learning of Black-Box Aggregator for Robust Nash Equilibrium AI翻译

  摘要：In this article, we study the robustness of the Nash equilibrium (NE) in aggregative games with coupling constraints. When the constraint parameters are uncertain, the associated NE might be perturbed. It is essential to find a robust NE satisfying all possible constraints affected by the uncertain parameters. Although some methods have been developed for robust NE, these results rely on complete information about the game. We instead consider a scenario when only the uncertain parameters and ...
• Offset-Free Model Predictive Control: Stability Under Plant-Model Mismatch AI翻译
  作者：Kuntz, Steven J.; Rawlings, James B.
  作者单位：University of California System; University of California Santa Barbara
  摘要：We present the first general stability results for nonlinear offset-free model predictive control (MPC). Despite over 20 years of active research, the offset-free MPC literature has not shaken the assumption of closed-loop stability for establishing offset-free performance. In this article, we present a nonlinear offset-free MPC design that is robustly stable with respect to the tracking errors, and thus achieves offset-free performance, despite the plant-model mismatch and persistent disturba...
• Stability Analysis for Hybrid Systems With Continuous and Logical Dynamics AI翻译
  作者：Wang, Qiyao; Sun, Jitao
  作者单位：Tongji University; Nantong University
  摘要：In this note, we address the stability problem for a class of hybrid systems, which contains continuous and logical dynamics. First, we introduce the so-called hybrid system in detail, and give the algebraic form of the system utilizing the semi-tensor product (STP, i.e., Cheng product) of matrices. Next, a new stability concept for the hybrid system is proposed by extending the definitions of set stability and exponential stability. After that, several stability criteria are presented by empl...

  摘要：Numerical optimization (solving optimization problems using digital computers) currently dominates but has three drawbacks: high energy consumption, poor scalability, and lack of an execution time certificate. To address these challenges, this article explores the recent resurgence of analog computers, proposing a novel paradigm of arbitrarily small execution-time-certified analog optimization (solving optimization problems via analog computers). To achieve ultra-low energy consumption, this p...
