• A New Event-Triggered Control Scheme for Stochastic Systems AI翻译
  作者：Yu, Hao; Chen, Tongwen; Hao, Fei
  作者单位：University of Alberta; Beihang University
  摘要：This article studies event-triggered control of stochastic linear discrete-time systems with discounted quadratic cost functions. A new dynamic event-triggering condition is proposed, which has simultaneously stochastic and deterministic features. The designed event-triggered control system ensures the control performance to be within a desirable level relative to that using periodic time-triggered control, while discarding the unnecessary transmissions. By adjusting the parameters, the propos...
• Self-Triggered Stabilization of Discrete-Time Linear Systems With Quantized State Measurements AI翻译

  摘要：We study the self-triggered stabilization of discrete-time linear systems with quantized state measurements. In the networked control system we consider, sensors may be spatially distributed and be connected to a self-triggering mechanism through finite data-rate channels. Each sensor independently encodes its measurements and sends them to the self-triggering mechanism. The self-triggering mechanism integrates quantized measurement data and then computes sampling times. Assuming that the clos...
• Measurement Difference Method: A Universal Tool for Noise Identification AI翻译
  作者：Kost, Oliver; Dunik, Jindrich; Straka, Ondrej
  作者单位：University of West Bohemia Pilsen
  摘要：This article deals with noise identification of a system described by the linear time-varying state-space model using correlation methods. In particular, the stress is laid on the measurement difference method (MDM) as a universal tool allowing estimation of moments and parameters of the state and measurement noises. The recent results are summarized in a common framework and the full (and weighted) MDM implementation is developed. This implementation provides unbiased and weakly consistent es...
• Nonlinear Stochastic Model Predictive Control: Existence, Measurability, and Stochastic Asymptotic Stability AI翻译
  作者：McAllister, Robert D.; Rawlings, James B.
  作者单位：University of California System; University of California Santa Barbara
  摘要：In this article, we establish a collection of new theoretical properties for nonlinear stochastic model predictive control (SMPC). Based on the concept of stochastic input-to-state stability (SISS), we define robust asymptotic stability in expectation (RASiE) and establish that nonlinear SMPC renders the origin of the closed-loop system RASiE. Moreover, we establish several new foundational results that have not been addressed in previous research. Specifically, we verify that, under basic reg...
• Sequential Detection of Replay Attacks AI翻译
  作者：Naha, Arunava; Teixeira, Andre; Ahlen, Anders; Dey, Subhrakanti

  摘要：One of the most studied forms of attacks on the cyber-physical systems is the replay attack. The statistical similarities of the replayed signal and the true observations make the replay attack difficult to detect. In this article, we address the problem of replay attack detection by adding watermarking to the control inputs and then perform resilient detection using cumulative sum (CUSUM) test on the joint statistics of the innovation signal and the watermarking signal, whereas existing work ...
• Event-Triggered Adaptive Control of Coupled Hyperbolic PDEs With Piecewise-Constant Inputs and Identification AI翻译
  作者：Wang, Ji; Krstic, Miroslav
  作者单位：Xiamen University; University of California System; University of California San Diego
  摘要：In this article, we present an event-triggered boundary control scheme with a, likewise, event-triggered batch least-squares parameter identification for a $2\times 2$ hyperbolic PDE-ODE system, where two coefficients of the in-domain couplings between two transport PDEs, and the system parameter of a scalar ODE, are unknown. The triggering condition is designed based on evaluating both the actuation deviation caused by the difference between the plant states and their sampled values, and the ...
• Finite-Time Stabilization and Optimal Feedback Control for Nonlinear Discrete-Time Systems AI翻译
  作者：Haddad, Wassim M.; Lee, Junsoo
  作者单位：University System of Georgia; Georgia Institute of Technology
  摘要：Finite-time stability involves dynamical systems whose trajectories converge to an equilibrium state in finite time. Sufficient conditions for finite-time stability have recently been developed in the literature for discrete-time dynamical systems. In this article, we build on these results to develop a framework for addressing the problem of optimal nonlinear analysis and feedback control for finite-time stability and finite-time stabilization for nonlinear discrete-time controlled dynamical ...

  摘要：Razumikhin-like theorems on hyperexponential and fixed-time stability of time-delay systems are proposed for both explicitly and implicitly defined Lyapunov functions. While the former method is useful for stability analysis, the latter approach is more suitable for control synthesis. Examples of systems that can be stabilized hyperexponentially and in fixed time are given. The control parameters tuning algorithm is presented in the form of linear matrix inequalities. The numerical simulations...
• Robust Model Predictive Control Using a Two-Step Triggering Scheme AI翻译
  作者：Deng, Li; Shu, Zhan; Chen, Tongwen
  作者单位：University of Alberta
  摘要：This article is concerned with event-triggered robust model predictive control for linear discrete-time systems with bounded disturbances. A two-step scheme involving a tentative verification of a triggering condition and a delayed triggering with a waiting horizon is proposed to reduce the average triggering rate and fully utilize the nominal optimal control sequence minimizing a quadratic cost function. The triggering condition and the waiting horizon are synthesized based on a prediction mo...
• Impulsive Stabilization of Systems With Control Delay AI翻译

  摘要：Input delay could lead to instability of an impulsive control system. However, the problem of input delay has been seldom studied. This work addresses the fundamentally important problem in impulsive control theory. By a novel approach, we establish Lyapunov-Razumikhin-type theorems on exponential stability of stochastic impulsive delay systems. Based on our fundamental results, we develop a foundational theory for the impulsive stabilization of stochastic delay systems with input delay. Our p...
