  摘要：Platooning of connected and autonomous vehicles (CAVs) has a significant potential for throughput improvement. However, the interaction between CAVs and non-CAVs may limit the practically attainable improvement due to platooning. To better understand and address this limitation, we introduce a new fluid model of mixed-autonomy traffic flow and use this model to analyze and design platoon coordination strategies. We propose a tandem-link fluid model that considers randomly arriving platoons sha...
• Boundary Control of Nonlinear ODE/Wave PDE Systems With a Spatially Varying Propagation Speed AI翻译

  摘要：We consider the boundary control of a nonlinear ordinary differential equation (ODE) actuated through a wave equation whose propagation speed is spatially varying. The ODE state is driven by the uncontrolled boundary of the wave equation. We design a nonlinear backstepping compensator to enable global asymptotic stability of the closed-loop system. We deduce the controller design and the stability proof by introducing a two-step backstepping transformation. The first transformation recasts the...

  摘要：In this article, we propose an attack-resilient control structure for a cyber-physical system (CPS) to enhance the CPS security against stealthy system integrity attacks that manipulate the state of the physical plant while undetected. With the help of nonlinear encoding/decoding components, the proposed structure can detect stealthy attacks and preserve the nominal performance without considering attacks. Meanwhile, for avoiding the eavesdropping of transmitted signals used to synchronize enc...
• Taylor Moment Expansion for Continuous-Discrete Gaussian Filtering AI翻译
  作者：Zhao, Zheng; Karvonen, Toni; Hostettler, Roland; Sarkka, Simo
  作者单位：Aalto University; Alan Turing Institute; Uppsala University
  摘要：This article is concerned with Gaussian filtering in nonlinear continuous-discrete state-space models. We propose a novel Taylor moment expansion (TME) Gaussian filter, which approximates the moments of the stochastic differential equation with a temporal Taylor expansion. Differently from classical linearization or Ito-Taylor approaches, the Taylor expansion is formed for the moment functions directly and in time variable, not by using a Taylor expansion on the nonlinear functions in the mode...
• Stabilization of Distributed Parameter Systems With Delays in the Boundary Based on Predictors AI翻译
  作者：Liu, Dongyi; Wang, Qingcong; Xu, Genqi

  摘要：This article is concerned with the controller design for distributed parameter systems with time delays in the boundary. An implementable control law is presented in light of a state predictor, and a feasible calculation scheme of this control law is provided based on the adjoint theory. The resulting closed-loop system is proved to be exponentially stable. As an application, a one-dimensional Schrodinger equation with a delay input is introduced and the numerical simulation verifies the feasi...
• Performance Evaluation of Distributed Linear Regression Kalman Filtering Fusion AI翻译

  摘要：This article studies the performance evaluation of distributed linear regression Kalman filtering fusion for nonlinear systems. Sufficient conditions are established for the convergence of the centralized fusion (CF) under the assumption of bounded estimation error covariance, and a measure of performance is derived from the convergence conditions. By the performance analysis, it can be found that the CF has a better performance than the distributed fusion with feedback, especially at the begi...
• Analytic Expressions in Stochastic Max-Plus-Linear Algebra and their Application in Model Predictive Control AI翻译
  作者：van den Boom, Ton J. J.; De Schutter, Bart
  作者单位：Delft University of Technology
  摘要：The class of max-plus-linear systems can model discrete event systems with synchronization but no choice. Model mismatch and/or disturbances can be characterized as stochastic uncertainties. In stochastic max-plus-linear systems one often needs to compute the expectation of a max-plus-scaling (MPS) function or the chance constraint of a MPS function. The algorithms available in literature are either computationally too expensive or only give an approximation. In this article, we derive an anal...
• Persistence of Delayed Complex Balanced Chemical Reaction Networks AI翻译
  作者：Zhang, Xiaoyu; Gao, Chuanhou
  作者单位：Zhejiang University
  摘要：In this article, we mainly focus on the persistence of delayed complex balanced systems. We first give the omega-limit set theorem for this kind of system which says that omega-limit set can be the single constant positive equilibrium or the set of constant equilibria on the boundaries. In addition, we derive several sufficient conditions to diagnose the persistence of delayed complex balanced chemical reaction network systems equipped with mass-action kinetics based on the situation of the bo...

  摘要：Robust global stabilization of nonlinear systems by observer-based feedback controllers is a challenging task. This article investigates the problem of designing observer-based stabilizing controllers for incrementally quadratic nonlinear systems with external disturbances. The nonlinearities considered in the system model satisfy the incremental quadratic constraints, which are characterized by incremental multiplier matrices and encompass many common nonlinearities. The simultaneous search f...
• Linear-Quadratic Time-Inconsistent Mean-Field Type Stackelberg Differential Games: Time-Consistent Open-Loop Solutions AI翻译
  作者：Moon, Jun; Yang, Hyun Jong
  作者单位：Hanyang University; Ulsan National Institute of Science & Technology (UNIST)
  摘要：In this article, we consider the linear-quadratic time-inconsistent mean-field type leader-follower Stackelberg differential game with an adapted open-loop information structure. The objective functionals of the leader and the follower include conditional expectations of state and control (mean field) variables, and the cost parameters could be general nonexponential discounting depending on the initial time. As stated in the existing literature, these two general settings of the objective fun...
