  摘要：This article studies an adaptive Kalman filter method based on model parameter ratio. The model parameter ratio theory is proposed for the first time, and the adaptive estimation problem is transformed into a constrained optimization problem. Compared with the existing Sage-Husa adaptive filtering algorithm, it can be seen that the application of this theory can more accurately estimate the process noise covariance and measurement noise covariance matrix, so that the algorithm has better filte...
• Incremental Versus Differential Approaches to Exponential Stability and Passivity AI翻译

  摘要：There are two main Lyapunov approaches to incremental stability analysis. One is to use incremental Lyapunov functions directly, and the other is based on so-called Finsler-Lyapunov functions via contraction analysis. A system is incrementally exponentially stable if it admits either an incremental or Finsler-Lyapunov function, and the converse is also true when the Jacobian of the drift vector field satisfies a boundedness assumption. However, the direct relation between these Lyapunov functi...
• Solutions for Multiple-Defender Single-Attacker Convex Target Guarding Games: Verification via Parametric Optimization AI翻译

  摘要：A zero-sum differential game is considered in which a team of defenders is tasked with cooperatively capturing a single attacker who seeks to breach a convex region (or target). We show that the equilibrium strategies of the agents can be computed via a convex program, which remains tractable even in high-dimensional cases as opposed to the direct solution of the Hamilton-Jacobi-Isaacs (HJI) equation. To that end, we mainly attempt to prove the validity of a candidate for the value of the game...
• Open-Loop H2/H∞ Control for Discrete-Time Mean-Field Stochastic Systems AI翻译

  摘要：This article is concerned with the finite-horizon H-2/H-infinity control problem about discrete-time mean-field linear stochastic systems with (x, u, v) -multiplicative noises. We first present a mean-field stochastic bounded real lemma (MF-SBRL), which gives a necessary and sufficient condition for the linear perturbation operator of mean-field systems to gain an H-infinity norm less than a prescribed disturbance attenuation level. Through a mean-field forward-backward stochastic difference e...
• Revisiting the Normal Form of Input-Output Linearization AI翻译
  作者：Maggiore, Manfredi
  作者单位：University of Toronto
  摘要：This article revisits the normal form arising in the context of input-output feedback linearization for nonlinear control systems possessing well-defined relative degree. The objective is to investigate the validity of the normal form in a neighborhood of the zero dynamics manifold, as opposed to a neighborhood of a point on the manifold. The two main results of the article are necessary and sufficient conditions under which the normal form exists in some neighborhood of the zero dynamics mani...
• Differentially Private Consensus Control for Discrete-Time Multiagent Systems: Encoding-Decoding Schemes AI翻译

  摘要：This article is concerned with the differentially private consensus control (DPCC) problem for linear discrete-time multiagent systems (MASs) under dynamic encoding-decoding schemes (EDSs), where the agents' initial states are the sensitive data to be protected from potential eavesdroppers. The EDS is deployed on each agent to compress the data before transmission so as to better utilize the limited network bandwidth. Differential privacy, as a performance metric, is introduced to evaluate the...
• Event-Triggered Robust MPC With Terminal Inequality Constraints: A Data-Driven Approach AI翻译
  作者：Deng, Li; Shu, Zhan; Chen, Tongwen
  作者单位：University of Alberta
  摘要：An event-triggered robust model predictive control (MPC) design is proposed for unknown systems using initially measured input-output data. A terminal inequality constraint is developed for the MPC optimization problem without any prior identification, resulting in a larger feasible region and a lower bound for the prediction horizon when compared with a terminal equality constraint. An event-triggered scheme associated with a local controller is designed to trigger the solution of the data-dr...
• Optimal Fixed Lockdown for Pandemic Control AI翻译

  摘要：As a common strategy of contagious disease containment, lockdowns inevitably have economic cost. The ongoing COVID-19 pandemic underscores the tradeoff arising from public health and economic cost. An optimal lockdown policy to resolve this tradeoff is desired. Here, we propose a mathematical framework of pandemic control through an optimal fixed stabilizing nonuniform lockdown, where our goal is to reduce the economic activity as little as possible while decreasing the number of infected indi...
• Computation of Safe Disturbance Sets Using Implicit RPI Sets AI翻译
  作者：Mulagaleti, Sampath Kumar; Bemporad, Alberto; Zanon, Mario
  摘要：Given a stable linear time-invariant system subject to output constraints, in this article, we present a method to compute a set of disturbances such that the reachable set of outputs matches as closely as possible the output constraint set, while being included in it. This problem finds application in several control design problems, such as the development of hierarchical control loops, decentralized control, supervisory control, robustness verification, etc. We first characterize the set of...
• What ODE-Approximation Schemes of Time-Delay Systems Reveal About Lyapunov-Krasovskii Functionals AI翻译
  作者：Scholl, Tessina H.; Hagenmeyer, Veit; Groell, Lutz
  作者单位：Helmholtz Association; Karlsruhe Institute of Technology
  摘要：This article proposes an approach to complete-type and related Lyapunov-Krasovskii functionals that neither requires knowledge of the delay-Lyapunov matrix function nor does it involve linear matrix inequalities. The approach is based on ordinary differential equations (ODEs) that approximate the time-delay system. The ODEs are derived via spectral methods, e.g., the Chebyshev collocation method (also called pseudospectral discretization) or the Legendre tau method. A core insight is that the ...
