摘要:This article is concerned with the mean-field stochastic cooperative linear-quadratic dynamic difference game in an infinite time horizon. First, the necessary and sufficient conditions for the stability in the mean-square sense and the stochastic Popov-Belevitch-Hautus eigenvector tests for the exact observability and exact detectability of mean-field stochastic linear difference systems are derived by the $\mathscr H-representation technique. Second, the relation between the solvability of t...

摘要:The basic reproduction number R0 is a fundamental quantity in epidemiological modeling, reflecting the typical number of secondary infections that arise from a single infected individual. While R0 is widely known to scientists, policymakers, and the general public, it has received comparatively little attention in the controls community. This note provides two novel characterizations of R0: a stability characterization and a geometric program characterization. The geometric program characteriz...

摘要:This article studies the cooperative tracking problem of heterogeneous Euler-Lagrange systems with an uncertain leader. Different from most existing works, system dynamic knowledge of the leader node is unaccessible to any follower node in our article. Distributed adaptive observers are designed for all follower nodes to simultaneously estimate the state and parameters of the leader node. The observer design does not rely on the frequency knowledge of the leader node, and the estimation errors...

摘要:This note presents a scalable approach for consensus stability analysis of a general class of large-scale multiagent system (MAS) with single delay considering directed and undirected graphs. It is shown that, under certain conditions satisfied by several protocols reported in the literature, consensus in MAS can be ensured by studying a set comprising a small number of quasipolynomials of reduced complexity. Specifically, if the graph is undirected, it suffices to guarantee the stability of o...

摘要:This work proposes a novel 2-D formation control scheme for acyclic triangulated directed graphs (a class of minimally acyclic persistent graphs) based on bipolar coordinates with (almost) global convergence to the desired shape. Prescribed performance control is employed to devise a decentralized control law that avoids singularities and introduces robustness against external disturbances while ensuring predefined transient and steady-state performance for the closed-loop system. Furthermore,...

摘要:this article, we study the verification of critical observability in discrete-event systems in which a plant and its observer are connected via an unreliable communication channel. We consider a communication protocol in which each packet sent from the plant consists of an event and the sequence number of the packet. We define two novel notions of critical observability called first, the k-step critical observability that requires that the critical states can be distinguished from noncritical ...

摘要:This study proposes an adaptive subsystem-based control (SBC) for systematic and straightforward nonlinear control of nth-order strict-feedback form (SFF) systems. By decomposing the SFF system to subsystems, a generic term (namely stability connector) can be created to address dynamic interactions between the subsystems. This 1) enables modular control design with global asymptotic stability, 2) such that the control design and its stability analysis can be performed locally at a subsystem le...

摘要:We investigate the stability conditions for remote state estimation of multiple linear time-invariant (LTI) systems over multiple wireless time-varying communication channels. We answer the following open problem: what is the fundamental requirement on the multisensor-multichannel system to guarantee the existence of a sensor scheduling policy that can stabilize the remote estimation system? In this note, we propose a novel policy construction and analytical framework and derive the necessary-...

摘要:This article is concerned with the boundary stabilization problem of an overhead crane with infinite memory. We show, under some assumptions of the memory kernel, that the problem is well-posed in the sense of semigroups theory. Furthermore, the uniform exponential stability of the solutions to the system is established by means of the frequency-domain method.

摘要:In this article, a predictor-based linearization approach is presented to solve the local asymptotic stabilization (LAS) problem of time-invariant nonlinear systems with a large constant input delay. Under stabilizability and detectability of the linearized time-delay system, we prove that LAS is achievable by either predictor-based state or output feedback controllers, which are designed based on the linearization. The predictor-based linearization technique developed in this research complem...
