  摘要：A weight-balanced network plays an important role in the exact convergence of a distributed optimization algorithm, but is not always satisfied in practice. Different from most of existing works focusing on designing distributed algorithms, in this article, we analyze the convergence of a well-known distributed projected subgradient algorithm over time-varying general graph sequences, i.e., the weight matrices of the network are only required to be row stochastic instead of doubly stochastic. ...

  摘要：In this article it is established that any jointly controllable, jointly observable, multichannel, discrete or continuous time linear system with a strongly connected neighbor {communication} graph can be exponentially stabilized with any pre-specified convergence rate using a time-invariant distributed linear control. As an illustration of how this finding can be used to deal with certain distributed tracking problems, a solution is given to a distributed set-point control problem for a conti...
• Stabilization of Linear Cyber-Physical Systems Against Attacks via Switching Defense AI翻译

  摘要：This article studies cyber-physical systems modeled with linear dynamics subject to attacks on the parameters. The attacker knows at all times the defense employed and injects a destabilizing piecewise Lipschitz time-varying attack signal. The defender does not know the specific attack and aims to preserve system stability. We propose a partitioning strategy for the set of possible attacks that generates a finite collection of candidate defenses such that, for each member of the partition, the...
• A Lyapunov Approach for the Exponential Stability of a Damped Timoshenko Beam AI翻译

  摘要：In this technical note, we consider the stability properties of a viscously damped Timoshenko beam equations with spatially varying parameters. With the help of the port-Hamiltonian framework, we first prove the existence of solutions and show, by the use of an appropriate Lyapunov function, that the system is exponentially stable and has an explicit decay rate. The explicit exponential bound is computed for an illustrative example for which we provide some numerical simulations.
• Periodic Event-Triggered MPC for Continuous-Time Nonlinear Systems With Bounded Disturbances AI翻译
  作者：Wang, Mengzhi; Cheng, Peng; Zhang, Zhenyong; Wang, Mufeng; Chen, Jiming
  作者单位：Zhejiang University; Guizhou University; Zhejiang University
  摘要：This article is concerned with periodic event-triggering laws in robust model predictive control (MPC) for continuous-time constrained nonlinear systems. The online optimal control problem solved at triggering times is introduced. A periodic static event-triggering condition, in which a fixed sampling time interval plays an important role in avoiding Zeno behavior, is presented to alleviate continuous checking of event detections. Then, a periodic dynamic event-triggering condition is investig...
• Continuous-Observation One-Sided Two-Player Zero-Sum Partially Observable Stochastic Game With Public Actions AI翻译
  作者：Zheng, Wei; Jung, Taeho; Lin, Hai

  摘要：The one-sided two-player zero-sum partially observable stochastic games (OTZ-POSG) have emerged as popular models recently, especially in the cyber-security literature. In this game, the state is hidden for one player but directly observed by the other player for whom we call the informed player. All existing OTZ-POSG models assumed that the observation space is discrete and the action of the informed player is private. However, these assumptions may become invalid in real applications. For ex...
• Encryption-Decryption-Based State Estimation With Multirate Measurements Against Eavesdroppers: A Recursive Minimum-Variance Approach AI翻译

  摘要：This article is concerned with the secure state estimation problem for a networked system with multirate measurements. The measurement data are transmitted to the estimator over a communication network, where an eavesdropper could intercept the transmitted information and generate the state estimates based on the overheard signals. In order to protect the privacy of the system state from information leakage, a novel encryptor is proposed to encrypt the measurement signals into codewords before...
• Characterization of a Family of Controllers for Networked Systems Under Nonuniform Communication and Network-Induced Delay AI翻译

  作者单位：Pakistan Institute of Engineering & Applied Science; Beijing Institute of Technology
  摘要：In this note, we characterize a family of discrete-time strictly causal stabilizing controllers for networked systems under nonuniform communication and network-induced delays. First, we absorb the feedback delay in the controller structure and parameterize a family of stabilizing controllers for the delay-free plant with some restrictions on the controller structure due to time delay. Then, we lift the feedback connection and choose the free parameter of the family in the lifted domain to inc...
• Communication Efficient Curvature Aided Primal-Dual Algorithms for Decentralized Optimization AI翻译

  摘要：This article presents a family of algorithms for decentralized convex composite problems. We consider the setting of a network of agents that cooperatively minimize a global objective function composed of a sum of local functions plus a regularizer. Through the use of intermediate consensus variables, we remove the need for inner communication loops between agents when computing curvature-guided updates. A general scheme is presented, which unifies the analysis for a plethora of computing choi...
• Maximal Admissible Disturbance Constraint Set for Tube-Based Model Predictive Control AI翻译
  作者：Xie, Huahui; Dai, Li; Sun, Zhongqi; Xia, Yuanqing
  作者单位：Beijing Institute of Technology
  摘要：Tube-based model predictive control (TMPC) is an outstanding control technique in robust control realms. However, the existing works are generally based on a priori known admissible sets of disturbances, i.e., disturbance constraint sets, the sizes of which are by default small enough such that the region of attraction is nonempty. If the size of the disturbance constraint set specified is too large, or even oversized in some particular direction, TMPC may not be capable of handling it and los...
