Abstract

This paper investigates the finite-time synchronization (FTS) of complex dynamic networks (CDNs) with impulsive control subject to actuator saturation. We develop a novel method that integrates the impulsive comparison principle and improved convex hull representation lemma of saturated function to derive LMI-based sufficient conditions for FTS, which are easy to verify. We also estimate the admissible set of initial values to ensure the validity of the lemma. Unlike previous work, we relax the monotonicity assumption on the Lyapunov function, which broadens our results’ applicability. Moreover, we formulate and solve an optimization problem to enlarge the admissible set under the LMI constraints, using YALMIP toolbox in MATLAB software. Finally, several numerical examples are proposed to demonstrate our results’ effectiveness and superiority.

具有脉冲控制和致动器饱和的复杂动态网络的有限时间同步：一种 LMI 方法

本文研究了受致动器饱和影响的具有脉冲控制的复杂动态网络（CDN）的有限时间同步（FTS）问题。我们开发了一种新方法，该方法综合了脉冲比较原理和饱和函数的改进凸壳表示法，推导出了基于 LMI 的 FTS 充分条件，这些条件易于验证。我们还估计了可接受的初始值集，以确保该 Lemma 的有效性。与之前的研究不同，我们放宽了 Lyapunov 函数的单调性假设，从而拓宽了结果的适用范围。此外，我们还利用 MATLAB 软件中的 YALMIP 工具箱提出并解决了一个优化问题，以扩大 LMI 约束下的可容许集。最后，我们提出了几个数值示例来证明我们结果的有效性和优越性。
