• Continuous-Time Penalty Methods for Nash Equilibrium Seeking of a Nonsmooth Generalized Noncooperative Game AI翻译
  作者：Sun, Chao; Hu, Guoqiang
  作者单位：Nanyang Technological University
  摘要：In this article, we propose centralized and distributed continuous-time penalty methods to find a Nash equilibrium for a generalized noncooperative game with shared inequality and equality constraints and private inequality constraints that depend on the player itself. By using the l(1) penalty function, we prove that the equilibrium of a differential inclusion is a normalized Nash equilibrium of the original generalized noncooperative game, and the centralized differential inclusion exponenti...
• A Fully Probabilistic Design for Tracking Control for Stochastic Systems With Input Delay AI翻译
  作者：Herzallah, Randa
  作者单位：Aston University
  摘要：This article studies model reference adaptive control (MRAC) for a class of stochastic discrete time control systems with time delays in the control input. In particular, a unified fully probabilistic control framework is established to develop the solution to the MRAC, where the controller is the minimizer of the Kullback-Leibler divergence between the actual and desired joint probability density functions of the tracking error and the controller. The developed framework is quite general, whe...
• Characterizations of Global Transversal Exponential Stability AI翻译

  摘要：We study the relationship between the global exponential stability of an invariant manifold and the existence of a positive semidefinite Riemannian metric which is contracted by the flow. In particular, we investigate how the following properties are related to each other (in the global case): 1) A manifold is globally transversally exponentially stable; 2) the corresponding variational system admits the same property; 3) there exists a degenerate Riemannian metric which is contracted by the f...
• Robust Dynamic Event-Triggered Coordination With a Designable Minimum Interevent Time AI翻译
  作者：Berneburg, James; Nowzari, Cameron
  作者单位：George Mason University
  摘要：This article revisits the classical multiagent average consensus problem for which many different event-triggered control strategies have been proposed over the last decade. Many of the earliest versions of these works conclude asymptotic stability without proving that Zeno behavior, or deadlocks, do not occur along the trajectories of the system. More recent works that resolve this issue either: propose the use of a dwell time that forces interevent times to be lower bounded away from zero bu...
• Strong Stability Analysis of Linear Delay-Difference Equations With Multiple Time Delays AI翻译
  作者：Song, Yunxia; Michiels, Wim; Zhou, Bin; Duan, Guang-Ren
  作者单位：Harbin Institute of Technology; KU Leuven
  摘要：This article is concerned with the strong stability problem of linear continuous-time delay-difference equations with multiple time delays. A family of linear matrix inequalities (LMIs), indexed by a positive integer k, is derived to assess strong stability. A time-domain interpretation of the proposed LMI-based condition is given in terms of a quadratic integral Lyapunov functional, which allows us to reveal relations with an existing result. The LMI condition can easily be reformulated in a ...
• Globally Exponentially Convergent Continuous Observers for Velocity Bias and State for Invariant Kinematic Systems on Matrix Lie Groups AI翻译
  作者：Chang, Dong Eui
  作者单位：Korea Advanced Institute of Science & Technology (KAIST)
  摘要：In this article globally exponentially convergent continuous observers for invariant kinematic systems on finite-dimensional matrix Lie groups has been proposed. Such an observer estimates, from measurements of landmarks, vectors, and biased velocity, both the system state and the unknown constant bias in velocity measurement, where the state belongs to the state-space Lie group and the velocity to the Lie algebra of the Lie group. The main technique is to embed a given system defined on a mat...
• Distributed Robust Adaptive Gradient Controller in Distance-Based Formation Control With Exogenous Disturbance AI翻译
  作者：Bae, Yoo-Bin; Lim, Young-Hun; Ahn, Hyo-Sung

  摘要：In this article, we present a distributed robust adaptive gradient controller for distance-based formation systems with exogenous disturbances. Based on the proposed controller, we consider two undirected formation topologies: Minimally infinitesimally rigid formation and nonminimally infinitesimally rigid formation. For both formation systems, we show that the distributed robust adaptive gradient controller guarantees a local stability of formation systems with exogenous disturbances. Further...

  摘要：This article establishes a robustness type result, namely, delay tolerance for stable stochastic systems under suitable conditions. We study the delay tolerance for stable stochastic systems and delayed feedback controls of such systems, where the delay can be statedependent or induced by the sampling-data. First, we consider systems with global Lipschitz continuous coefficients and show that when the original stochastic system without delay is pth moment exponentially stable, the system with ...
• Tracking Performance Limitations of Networked Control Systems With Repeated Zeros and Poles AI翻译

  摘要：In this article, the performance limitations problem are investigated for a class of signal-input, signal-output networked control systems with repeated zeros and poles. The additive white noise is adopted in the communication channel. The tracking performance limitations are investigated based on a two-degree of freedom (2DOF) controller. The results demonstrate that the multiplicity of nonminimum phase (NMP) zeros and unstable poles of the plant can affect the tracking performance limitation...

  摘要：This article deals with computational complexity of various problems related to the zero controllability of a discrete-time linear time-invariant system, assuming that purely structural conditions at the level of the connections between the system states (i.e., state-connections) and the connections from the inputs to the states (i.e., input-connections) are known. Given a generically zero controllable system, we consider the following problems: i) find a minimal set of input-connections whose...
