摘要:In this article, the event-triggered control problem for linear systems with uncertainties is addressed. A model-based dynamic event-triggered transmission strategy is proposed for linear systems, and for systems that can be decomposed into interconnected subsystems, a distributed model-based dynamic event-triggered transmission strategy is also proposed with transmission delays and transmission protocols in the networks. The whole systems are modeled into a hybrid system framework by introduc...

摘要:This article considers the small-time local controllability (STLC) of switched nonlinear systems (SNSs). First, the original SNS is associated with a nilpotent Lie algebra, on which the solutions of the SNS are approximated by the hybrid Lie power series. Second, the concepts of high-order control variations and bad Lie brackets are defined for SNSs from a geometrical point of view. This helps to establish a new high-order sufficient STLC condition that is closely related to neutralized bad Li...

摘要:An output robust adaptive control is designed for a class of Lipschitz nonlinear systems under assumption that the measurements are available with a constant bias and the state equations linearly parameterized by unknown parameters and external disturbances. A dynamic state reconstruction (synthesis of an observer) is avoided by using delayed values of the output in the feedback and adaptation laws. The analysis of robust stability for the resulted time-delay system is performed by using the L...

摘要:In this article, we presented guaranteed independent and uniformmultivariable stabilitymargins for the H-infinity/LTR control, both in continuous and discrete time. In previous works, it was shown that the H-infinity/LTR control generalizes the linear quadratic Gaussian (LQG)/LTR setup, allowing the designer to better impose bounds on the complementary sensitivity frequency peak in the loop-shaping procedure. In this article, we extend this result by showing that H-infinity/LTR control is able...

摘要:Team problems, in which multiple agents act to minimize a common expected cost function, are generally intractable. The problem of establishing the existence of team-optimal strategies has received significant attention in the past decade. In this article, we present a proof of the existence of team-optimal strategies in a class of teams in which observations are realized in a countable set and are shared among the agents and the action sets are noncompact. We derive sufficient conditions unde...

摘要:In this article, we study the problem of estimating the state of the linearized Kermack-McKendrick partial differential equation (PDE) model in real time. Especially, we assume that the model contains two kinds of delays. One of them is contained in the nonlocal boundary condition, which expresses the latent period of infection. The other is an observation delay, which corresponds to the time needed for counting the number of infected people at an infection elapsed time. The element of time la...

摘要:We investigate how the graph topology influences the robustness to noise in undirected linear consensus networks. We measure the structural robustness by using the smallest possible value of steady-state population variance of states under the noisy consensus dynamics with edge weights from the unit interval. We derive tight upper and lower bounds on the structural robustness of networks based on the average distance between nodes and the average node degree. Using the proposed bounds, we char...

摘要:Distributed bandit online convex optimization with time-varying coupled inequality constraints is considered, motivated by a repeated game between a group of learners and an adversary. The learners attempt tominimize a sequence of global loss functions and at the same time satisfy a sequence of coupled constraint functions, where the constraints are coupled across the distributed learners at each round. The global loss and the coupled constraint functions are the sum of local convex loss and c...

摘要:We develop a predictor-based distributed feedback controller that guarantees exponential stability for a class of reaction-diffusion partial differential equations (PDEs) subject to spatially varying input delay. The delay depends on the location of the input in the spatial domain. In order to design a distributed controller to compensate the spatially varying delay, we first introduce an implicit backstepping transformation, which contains the state of the target system on both sides of the d...

摘要:This article investigates the distributed online optimization problem over a multi-agent network subject to local set constraints and coupled inequality constraints, which has a lot of applications in many areas, such as wireless sensor networks, power systems, and plug-in electric vehicles. In this problem, the cost function at each time step is the sum of local cost functions with each of them being gradually revealed to its corresponding agent, and meanwhile only local functions in coupled ...
