摘要：The problems of stability and stabilization are addressed for a class of nonlinear mechanical systems with distributed delays. Assuming that potential and kinetic energy functions are homogeneous of different degrees, it is shown that the global asymptotic stability of the zero solution for an auxiliary delay-free nonlinear system implies the local asymptotic stability for the original model with distributed delay. The influence of additional nonlinear and time-varying perturbations is investi...

摘要：This article characterizes the state-space representation and control Lyapunov theory for continuous-time Markov networks (CT-MNs), which constitute a family of Markov chains endowed with network structures, serving as the theoretical basis for the investigations of several swarm behaviors. First, the notions of coupling Markov property and conditional independent property are introduced, enabling a CT-MN to be merged as a decentralized continuous-time Markov chain (CT-MC). Then, explicit form...

摘要：Two-player zero-sum games often rely on solving the game algebraic Riccati equation (GARE) in the linear case. However, existing approaches for solving the GARE typically require stringent initial conditions, which pose challenges for practical implementation. Although the double-loop iterative scheme is commonly used to learn the GARE solution, the single-loop iterative method is more time-efficient during computation. Therefore, we develop a novel data-driven single-loop iterative method to ...

摘要：In this article, we study privacy-preserving resilient vector consensus in multiagent systems against faulty agents, where normal agents can achieve consensus within the convex hull of their initial states while protecting state vectors from being disclosed. Specifically, we consider a modification of an existing algorithm known as approximate distributed robust convergence using centerpoints (ADRC), i.e., privacy-preserving ADRC (PP-ADRC). Under PP-ADRC, each normal agent introduces multivari...

摘要：Novel nonlinear functions are introduced to construct first-order nonlinear filters to address the following critical issues encountered in widely used dynamic surface control (DSC) methods. First, there is no guideline for selecting the parameters of the first-order filters, which depend on the upper bounds of complicated composite functions. Second, the parameters of the filters cannot be obtained for adaptive dynamic surface control (ADSC) in the presence of totally unknown parameters since...

摘要：To tackle the challenge of effectively stabilizing an inherently unstable highly nonlinear stochastic hybrid system while simultaneously minimizing costs, this article introduces a novel control strategy termed aperiodically delayed intermittent control (ADIC), grounded in discrete-time observations. Diverging from the conventional stochastic hybrid system driven by Brownian motion, we adopt Levy noise to characterize the random perturbations, which possess the capacity to capture the disconti...

摘要：The resilient consensus problem is investigated in this article for a class of networked Euler-Lagrange systems with event-triggered communication in the presence of Byzantine attacks. One challenge that we face in addressing the considered problem is the inapplicability of existing resilient decision algorithms designed for 1-D multiagent systems. This is because the networked Euler-Lagrange systems fall into the category of multi-dimensional multiagent systems with coupling among state vecto...

摘要：In this article, we present a distributed control system design for the consensus of nonlinear multiagent systems subject to non-ideal communication channels and external disturbances. The agents are modeled as a class of perturbed port-Hamiltonian systems-a formalism to model complex physical and engineering systems-and the imperfection in the communication channels is represented by time-delays that are assumed to be bounded. We show that the proposed distributed controller ensures global as...

摘要：This article considers the problem of online multirobot motion planning with general nonlinear dynamics subject to unknown external disturbances. We propose dSLAP, a distributed safe learning and planning framework that allows the robots to safely navigate through the environments by coupling online learning and motion planning. Gaussian process regression is used to online learn the disturbances with uncertainty quantification. The planning algorithm ensures collision avoidance against the le...

摘要：This article explores the application of asynchronous intermittent control (AIC) in stochastic highly nonlinear delayed systems (SHNDSs) with regime-switching diffusion, and studies the pth moment exponential stability of the controlled systems. For SHNDSs that no longer satisfy linear growth conditions but rather polynomial growth conditions, a new Lyapunov functional is constructed, which includes both pth power and qth power terms (q>p >= 2). In addition, this article introduces AIC into SH...
