Abstract

In this article, for switched nonlinear time-delay multi-agent systems (MASs) under directed graphs, an adaptive event-triggered (ET) consensus problem is investigated. Each agent's switching signal is allowed to be arbitrary and asynchronous. To save communication resources, an adaptive ET consensus strategy is designed. In addition, the Pade approximation approach is introduced to transform the system into an input delay-free system. A Lyapunov–Krasovskii functional is employed to analyze the effect of time-varying delays on system stability. It is proved that the consensus errors of switched NMASs are bounded, and the Zeno behavior does not exist. Finally, the presented strategy's effectiveness is verified by simulation results.

具有状态和输入延迟的交换式非线性多代理系统的分布式自适应事件触发共识

摘要本文针对有向图下的交换式非线性时延多代理系统（MAS），研究了自适应事件触发（ET）共识问题。允许每个代理的切换信号是任意和异步的。为了节省通信资源，设计了一种自适应 ET 共识策略。此外，还引入了 Pade 近似方法，将系统转化为无输入延迟系统。利用 Lyapunov-Krasovskii 函数分析时变延迟对系统稳定性的影响。结果证明，交换式 NMAS 的共识误差是有界的，不存在 Zeno 行为。最后，模拟结果验证了所提出策略的有效性。

期刊介绍： The International Journal of Adaptive Control and Signal Processing is concerned with the design, synthesis and application of estimators or controllers where adaptive features are needed to cope with uncertainties.Papers on signal processing should also have some relevance to adaptive systems. The journal focus is on model based control design approaches rather than heuristic or rule based control design methods. All papers will be expected to include significant novel material. Both the theory and application of adaptive systems and system identification are areas of interest. Papers on applications can include problems in the implementation of algorithms for real time signal processing and control. The stability, convergence, robustness and numerical aspects of adaptive algorithms are also suitable topics. The related subjects of controller tuning, filtering, networks and switching theory are also of interest. Principal areas to be addressed include: Auto-Tuning, Self-Tuning and Model Reference Adaptive Controllers Nonlinear, Robust and Intelligent Adaptive Controllers Linear and Nonlinear Multivariable System Identification and Estimation Identification of Linear Parameter Varying, Distributed and Hybrid Systems Multiple Model Adaptive Control Adaptive Signal processing Theory and Algorithms Adaptation in Multi-Agent Systems Condition Monitoring Systems Fault Detection and Isolation Methods Fault Detection and Isolation Methods Fault-Tolerant Control (system supervision and diagnosis) Learning Systems and Adaptive Modelling Real Time Algorithms for Adaptive Signal Processing and Control Adaptive Signal Processing and Control Applications Adaptive Cloud Architectures and Networking Adaptive Mechanisms for Internet of Things Adaptive Sliding Mode Control.
