• Solution of the Continuous Time Bilinear Quadratic Regulator Problem by Krotov's Method AI翻译
  作者：Halperin, Ido
  作者单位：Ariel University
  摘要：This article contributes to the field of optimal control of bilinear systems. It concerns a continuous time finite-dimensional bilinear state equation with a quadratic performance index to be minimized. The state equation is nonautonomous and comprises a deterministic a priori known excitation. The control trajectory is constrained to an admissible set without a specific structure. The performance index is a functional quadratic in the state variables and control signals. The Krotov's method i...
• Topological Analysis of Vector-Field Guided Path Following on Manifolds AI翻译

  摘要：A path-following control algorithm enables a system's trajectories under its guidance to converge to and evolve along a given geometric desired path. There exist various such algorithms, but many of them can only guarantee local convergence to the desired path in its neighborhood. In contrast, the control algorithms using a well-designed guiding vector field can ensure almost global convergence of trajectories to the desired path; here, almost means that in some cases, a measure-zero set of tr...
• 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...
• On Preserving-Excitation Properties of Kreisselmeier's Regressor Extension Scheme AI翻译

  摘要：In this article, we consider the excitation preservation problem of Kreisselmeier's regressor extension scheme. We analyze this problem within the context of the dynamic regressor extension and mixing procedure. The well-known qualitative result is that such a scheme preserves excitation. We perform a quantitative analysis and derive lower bounds on the resulting regressor signal considering both persistent and interval excitation cases. We also show that the resulting signal is excited if and...
• Distributed Adaptive Tracking Control for High-Order Nonlinear Multiagent Systems Over Event-Triggered Communication AI翻译
  作者：Deng, Chao; Wen, Changyun; Wang, Wei; Li, Xinyao; Yue, Dong

  摘要：In this article, we investigate the consensus problem for high-order nonlinear multiagent systems (MASs) with an uncertain leader under event-triggered communication. Compared with the existing consensus results for nonlinear MASs under event-triggered communication, the class of systems considered is more general, while achieving better performance in term of asymptotic tracking. To estimate the unknown parameters of the uncertain leader, distributed intermediate parameter estimators based on...
• Dynamic Controller That Operates Over Homomorphically Encrypted Data for Infinite Time Horizon AI翻译
  作者：Kim, Junsoo; Shim, Hyungbo; Han, Kyoohyung

  摘要：In this article, we present a dynamic feedback controller that computes the next state and the control signal over encrypted data using homomorphic properties of cryptosystems, whose performance is equivalent to the linear dynamic controllers over real-valued data. Assuming that the input as well as the output of the plant is encrypted and transmitted back to the controller, it is shown that the state matrix of any linear time-invariant controller can be always converted to a matrix of integer...
• Characterization of Input-Output Negative Imaginary Systems in a Dissipative Framework AI翻译
  作者：Lanzon, Alexander; Bhowmick, Parijat
  作者单位：University of Manchester
  摘要：this article, we define the notion of sta-ble input-output negative imaginary (IONI) systems. This new class captures and unifies all the existing stable sub-classes of negative imaginary (NI) systems and is capable of distinguishing between the strict subclasses (e.g., strongly strictly negative imaginary, output strictly negKative imaginary (OSNI), input strictly negative imaginary, etc.) in the literature. In addition to a frequency-domain definition, the proposed IONI class has been charac...
• Data-Driven Simulation of Generalized Bilinear Systems via Linear Time-Invariant Embedding AI翻译

  摘要：Nonparameteric representations of linear time-invariant systems that use Hankel matrices constructed from data are the basis for data-driven simulation and control. This article extends the approach to data-driven simulation of a class of nonlinear systems, called generalized bilinear. The generalized bilinear class includes Hammerstein, finite-lag Volterra, and bilinear systems. The key step of the generalization is an embedding result that is of independent interest. The behavior of a nonlin...
• Explaining the Mystery of Periodicity in Inter-Transmission Times in Two-Dimensional Event-Triggered Controlled Systems AI翻译

  摘要：Motivated by scenarioswhere the communication or the computation resources are limited, event-triggered control consists of transmitting data between the plant and the controller according to the actual system needs and not the elapsed time since the last transmission instant as in traditional sampled-data control, so that the desired control objective is achieved. A range of techniques are nowadays available to design event-triggered controllers. However, we generally have only very little in...
• An Output Feedback Stabilizer for Uncertain MIMO Nonlinear Systems: Nonlinear Nominal Input Gain Function AI翻译
  作者：Ha, Wonseok; Back, Juhoon
  作者单位：Kwangwoon University
  摘要：This article presents a robust output feedback stabilizer for multi-input-multi-output nonlinear systems subject to external disturbances and system uncertainties. We assume that the system has a well-defined vector relative degree and the zero dynamics is input-to-state stable. Based on the assumption that there exists a state feedback controller that makes the origin of the nominal closed-loop system asymptotically stable, we present an output feedback stabilizer that recovers the stability ...
