摘要：A new zero-order algorithm to solve the maximum hands-off control is proposed. Maximum hands-off control is discretized into a convex linear programming problem by zero-order-hold discretization. The first-order necessary conditions for linear programming problems are presented. To ensure that the switching points meet the allowable error, the jump function is used to preliminarily determine the switching points of the control variable. The finite switch number lemma for the maximum hands-off ...

摘要：This article proposes a novel sufficient condition for the incremental input-to-state stability of a class of recurrent neural networks (RNNs). The established condition is compared with others available in the literature, showing to be less conservative. Moreover, it can be applied for the design of incremental input-to-state stable RNN-based control systems, resulting in a linear matrix inequality constraint for some specific RNN architectures. The formulation of nonlinear observers for the ...

摘要：In this article, we first study the leader-following output synchronization problem for a class of uncertain nonlinear multi-agent systems over jointly connected switching networks. Our approach integrates the output-based adaptive distributed observer, the conventional adaptive control technique, and the output regulation theory. Compared with the existing results, our control law only relies on the output of the leader instead of the state of the leader and allows the followers and the leade...

摘要：This note studies output-feedback consensus of linear multiagent systems (MASs) on directed graphs. In view of limited communication resources in MAS tasks, the aim of this note is to reduce interagent communication. A fully distributed dynamic output-feedback protocol is proposed, where an event-triggered strategy is designed to determine when to exchange protocol states while a time-triggered one is designed to determine when to sample relative outputs. Design conditions are first establishe...

摘要：In this article, we are concerned with an adaptive output tracking problem for 1-D antistable wave equations with unknown harmonic disturbance and reference signals which have both unknown frequencies and amplitudes. The output and disturbance are noncollocated to the control input. First, we construct an auxiliary system and internal model dynamic to restructure the measurable tracking error such that the error consists of these available states. Then, an adaptive method is used to estimate t...

摘要：This article is devoted to stability analysis of stochastic nonlinear delay systems subject to multiple periodic impulses. By means of the stochastic analysis technique and improved Razumikhin method, we obtain several novel stability criteria under the combined action of impulsive disturbance and impulsive control. It is worth noting that the definition of globally weakly stochastically exponential stability is introduced and this article is the first attempt to study such stability notion fo...

摘要：This article investigates the stabilization of a class of stochastic nonhomogeneous semi-Markov jump systems (SNSMJSs). As a result of incomplete access to the system's state and the occurrence of asynchronous phenomena that occur during information transmission, the control design of the SNSMJSs becomes significantly more complicated. To tackle such a challenge, an observer-based asynchronous controller embedded with a hidden Markov model is proposed. First, an algebraic relationship among tr...

摘要：The Lyapunov stability theory is developed for absorbing continuous-time Markov chains (CT-MCs) in this technical note. The derived stability criteria are all necessary and sufficient for absorbing CT-MCs and set absorbing CT-MCs, where Lyapunov functions can be constructed in a polynomial amount of time with respect to the cardinality of state spaces. Furthermore, the gap between Lyapunov functions of the CT-MCs and of the discrete-time Markov chains is bridged by the feature that the length ...

摘要：Gradient-based first-order convex optimization algorithms find widespread applicability in a variety of domains, including machine learning tasks. Motivated by the recent advances in fixed-time stability theory of continuous-time dynamical systems, we introduce a generalized framework for designing accelerated optimization algorithms with strongest convergence guarantees that further extend to a subclass of nonconvex functions. In particular, we introduce the GenFlow algorithm and its momentum...

摘要：Extremum seeking control aims at determining and keeping the output of a nonlinear static or dynamic map on its unknown extremum point. In the literature, despite considering an unknown objective function in the real-time optimization problem, it is mandatory to know whether the extremum point is a maximum or a minimum, which is characterized by means of the Hessian sign of the nonlinear scalar map. This article proposes that the process of extremum seeking occurs independently of the Hessian ...
