  摘要：For a retarded nonlinear system with a Lipschitz nonlinearity on bounded sets outside the origin, this article proposes necessary conditions for application of the Lyapunov-Razumikhin method. The presented conditions are illustrated on the classes of linear and nonlinear homogeneous systems.
• Mixed Populations of Coordinators, Anticoordinators, and Imitators: Stochastic Stability AI翻译
  作者：Rajaee, Mohaddeseh; Ramazi, Pouria

  摘要：Decision-making mechanisms are typically either of imitation, that is, to copy the action of successful fellows, coordination, that is, to take an action if enough fellows have done so, or anticoordination, that is to take an action if few fellows have done so. The resulting decision-making dynamics of a mixture of individuals following these three mechanisms may either eventually reach an equilibrium state where no one tends to switch strategies or enter a nonsingleton positively invariant se...
• Analysis of H∞ Performance for Multiagent Networks AI翻译
  作者：Wang, Jiamin; Liu, Jian; Zheng, Yuanshi; Xi, Jianxiang

  摘要：In this article, we analyze the H(infinity )performance of the first-order continuous-time multiagent consensus network and that of the corresponding sampled-data network in the presence of external disturbances. First, we build the quantitative relation between the H-infinity performance and the eigenvalues of directed graph Laplacian for the continuous-time multiagent network. Second, we establish the analytic expression of H-infinity performance for the sampled-data multiagent network, whic...
• Approximation by Simple Poles-Part I: Density and Geometric Convergence Rate in Hardy Space AI翻译
  作者：Fisher, Michael W.; Hug, Gabriela; Dorfler, Florian

  摘要：Optimal linear feedback control design is a valuable but challenging problem due to the nonconvexity of the underlying optimization and the infinite dimensionality of the Hardy space of stabilizing controllers. A powerful class of techniques for solving optimal control problems involves using reparameterization to transform the control design into a convex but infinite-dimensional optimization. To make the problem tractable, historical work focuses on Galerkin-type finite-dimensional approxima...
• Distributed Model Predictive Consensus of MASs Against False Data Injection Attacks and Denial-of-Service Attacks AI翻译
  作者：Li, Zhengcai; Shi, Yang; Xu, Shengyuan; Xu, Huiling; Dong, Lewei

  摘要：This article provides a secure distributed output feedback model predictive control (DOFMPC) solution for the leader-following consensus problems of homogeneous linear disturbed multi-agent systems against multiple cyber attacks. The false data injection (FDI) attacks on the sensor-controller communication channel and denial-of-service (DoS) attacks on the controller-actuator communication channel occur simultaneously. To defend against dual-channel multiple attacks, we propose a secure DOFMPC...
• Static Output Feedback Sliding Mode Control With Structured Sliding Surface Matrices AI翻译
  作者：Wu, Jenq-Lang
  作者单位：National Taiwan Ocean University
  摘要：On the basis of the barrier method, a unified approach for the static output feedback sliding mode control of linear control systems with matched uncertainty is addressed. Without coordinate transformations, a structured static output feedback sliding surface matrix is obtained by solving a constrained minimization problem, and then, a globally stabilizing static output feedback sliding mode controller can be constructed directly. The Lagrange multiplier method is used to derive the necessary ...
• Model Predictive Control for Quadcopters With Almost Global Trajectory Tracking Guarantees AI翻译
  作者：Andrien, A. R. P.; Lefeber, E.; Antunes, D. J.; Heemels, W. P. M. H.
  作者单位：Eindhoven University of Technology
  摘要：This article provides a new method for trajectory tracking for quadcopters following a cascaded control approach with formal closed-loop tracking guarantees. An outer-loop model predictive controller generates twice differentiable acceleration references, which provide attitude, angular velocity, and acceleration references for a nonlinear inner-loop controller. The model predictive controller allows for tracking of references while explicitly considering that the thrust of the quadcopter is u...
• Connections Between Integral Quadratic Constraints and Dissipativity AI翻译
  作者：Khong, Sei Zhen; Lanzon, Alexander
  作者单位：National Sun Yat Sen University; University of Manchester
  摘要：We show that a recent dissipativity approach to feedback stability analysis of potentially open-loop unstable systems, which encompasses the classical soft integral quadratic constraint (IQC) theorem, may be recovered by hard IQC theory. The latter is known to be subsumable by the more general soft IQC theory endowed with homotopies that are continuous in the gap topology. In addition, we demonstrate how the aforementioned classical soft IQC theorem, initially introduced for the analysis of a ...
• Dynamic Gain Adaptation in Linear Quadratic Regulators AI翻译
  作者：Komaee, Arash
  作者单位：Southern Illinois University System; Southern Illinois University
  摘要：In feedback control of dynamical systems, the choice of a higher loop gain is typically desirable to achieve a faster closed-loop dynamics, smaller tracking error, and more effective disturbance suppression. Yet, an increased loop gain requires a higher control effort, which can extend beyond the actuation capacity of the feedback system and intermittently cause actuator saturation. To benefit from the advantages of a high feedback gain and simultaneously avoid actuator saturation, this articl...
• Secure Zonotopic Set-Membership State Estimation for Multirate Complex Networks Under Encryption-Decryption Mechanism AI翻译
  作者：Yang, Hao; Yan, Huaicheng; Li, Yan; Wen, Paul; Yang, Fuwen

  摘要：In this article, the zonotope-based distributed set-membership state estimation problem is considered for a class of nonlinear multirate complex networks (MRCN) subjected to unknown but bounded (UBB) noises and eavesdropping attacks. Both the process and measurement noises and the system linearization errors are constrained within known zonotopes. To ensure the communication security between the sensor and the estimator, an encryption-decryption mechanism (EDM) is proposed to prevent data from...
