  摘要：Optimization with gradient tracking is particularly notable for its superior convergence results among the various distributed algorithms, especially in the context of directed graphs. However, privacy concerns arise when gradient information is transmitted directly which would induce more information leakage. Surprisingly, literature has not adequately addressed the associated privacy issues. In response to the gap, our article proposes a privacy-preserving distributed optimization algorithm ...
• Stochastic LQ Optimal Control With Initial and Terminal Constraints AI翻译
  作者：Liu, Jingmei; Xu, Juanjuan; Zhang, Huanshui; Fu, Minyue

  摘要：In this article, we consider the discrete-time stochastic linear quadratic (LQ) optimal control with both initial and terminal constraints. The main contribution includes two aspects: one is to provide a necessary and sufficient condition for the exact reachability of stochastic systems; the other is to characterize the solvability condition of the constrained stochastic LQ optimal control problem based on the exact reachability of the stochastic systems and obtain the explicitly optimal contr...
• Active Fault Isolation for Discrete Event Systems AI翻译

  摘要：In practice, a supervisor can often not only disable some events, but also enforce the occurrence of some events prior to the occurrence of other events. In this article, we combine these two control mechanisms to synthesize a more powerful supervisor. The control goal is to design an isolation supervisor, which ensures in the closed-loop system, faults are fault isolatable in the sense that after a fault occurs, we can determine which type the fault belongs to by observing the output of the c...

  摘要：In this article, we consider the problem of computing from data guaranteed set-valued over-approximations of unknown monotone functions with additive disturbances. We provide a characterization of a simulating map that provably contains all monotone functions that are consistent with the data. This map is also minimal in the sense that any set-valued map containing all consistent monotone functions would also include the map we are proposing. We show that this minimal simulating map is interva...
• Formal Analysis of the Sampling Behavior of Stochastic Event-Triggered Control AI翻译
  作者：Delimpaltadakis, Giannis; Laurenti, Luca; Mazo Jr, Manuel

  摘要：Analyzing event-triggered control's (ETC) sampling behavior is of paramount importance, as it enables formal assessment of its sampling performance and prediction of its sampling patterns. In this work, we formally analyze the sampling behavior of stochastic linear periodic ETC (PETC) systems by computing bounds on associated metrics. Specifically, we consider functions over sequences of state measurements and intersampling times that can be expressed as average, multiplicative or cumulative r...
• Remote State Estimation of Steered Systems With Limited Communications: An Event-Triggered Approach AI翻译

  摘要：In this article, an approach is proposed for the remote observation of a dynamical system through a data-rate constrained communication channel. The focus is put on discrete-time systems with a Lipschitz nonlinearity, driven by an external signal, and subject to bounded state perturbation and measurement error. The problem at hand is providing estimates of system's state at a remote location, which is connected via a channel, which can only sent limited numbers of bits per unit of time. A solu...
• Finite-Time Stabilization of Uncertain Markovian Jump Systems: An Adaptive Gain-Scheduling Control Method AI翻译
  作者：Cao, Zhiru; Niu, Yugang; Peng, Chen
  作者单位：Shanghai University; East China University of Science & Technology
  摘要：This article addresses the stochastic finite-time stabilization problem for a class of Markovian jump systems with polytopic uncertainties. First, an adaptive gain-scheduling-based control design method is well proposed. Compared with the traditional common/parameter-independent control method, the polytopic structure characteristic is well used via approximating uncertain parameters in controller design, which might reduce the conservatism and improve the flexibility of control design. Second...
• Event-Triggered Control Systems Under Stochastic Pulsing Denial-of-Service Attacks AI翻译
  作者：Zhang, Dandan; Jin, Xin; Su, Hongye
  作者单位：Zhejiang University; Fudan University; East China University of Science & Technology
  摘要：By designing a time-regularized (Zeno-free) event-triggered strategy for the state-feedback control law, this article considers the stochastic stabilization of networked control systems, where the networked communication is constrained by stochastic pulsing denial-of-service (DoS) attacks. The attacks' cardinal number is supposed to be subject to Poisson distribution, so the interattack time, i.e., the time between two consecutive attack instants, is subject to exponential distribution. The co...
• On ISS With Respect to Average Value of Disturbances: A Time-Delay Approach AI翻译
  作者：Efimov, Denis; Fridman, Emilia
  作者单位：Inria; Centre National de la Recherche Scientifique (CNRS); CNRS - Institute for Information Sciences & Technologies (INS2I); Universite de Lille; Centrale Lille; Tel Aviv University
  摘要：For input-affine nonlinear dynamical systems, an input-to-state stability analysis with respect to (weighted) average values of exogenous perturbations is proposed. The time-delay method is used to represent the system in a suitable form for investigation: A kind of neutral-type differential equation. The introduced approach allows the asymptotic gains with respect to zero-mean periodic signals to be evaluated for nonlinear systems (an analogue of Bode magnitude plot), as well as for integral ...
• Attitude Tracking for Rigid Bodies Using Vector and Biased Gyro Measurements AI翻译
  作者：Espindola, Eduardo; Tang, Yu
  作者单位：NingboTech University
  摘要：In this article, rigid-body attitude tracking using vector measurements and gyro rate is studied. A gyro-bias observer and an attitude tracking controller are first devised, which in combination ensure the exponential stability of the desired equilibrium of the overall system. To address inertia-matrix uncertainties and external disturbances, an adaptive controller relying on a modified gyro-bias observer and a disturbance estimator are then developed. Simulations are included to illustrate th...
