This article is concerned with the issue of l₂-l∞ state estimation for nonlinear coupled networks, where the variation of coupling mode is governed by a set of switching signals satisfying a persistent dwell-time property. To solve the problem of data collisions in a constrained communication network, the round-robin protocol, as an important scheduling strategy for orchestrating the transmission order of sensor nodes, is introduced. Redundant channels with signal quantization are used to improve the reliability of data transmission. The main purpose is to determine an estimator that can guarantee the exponential stability in mean square sense and an l₂-l∞ performance level of the estimation error system. Based on the Lyapunov method, sufficient conditions for the addressed problem are established. The desired estimator gains can be obtained by addressing a convex optimization case. The correctness and availability of the developed approach are finally explained via two illustrative examples.

服从轮询协议的持久停留时间交换耦合网络的12-l∞状态估计。

本文涉及非线性耦合网络的l 2 -l∞状态估计问题，其中耦合模式的变化由一组满足持久驻留时间特性的开关信号控制。为了解决约束通信网络中的数据冲突问题，引入循环协议作为协调传感器节点传输顺序的重要调度策略。具有信号量化功能的冗余通道用于提高数据传输的可靠性。主要目的是确定一种估计器，该估计器可以保证均方意义上的指数稳定性和估计误差系统的I 2 -I∞性能水平。基于Lyapunov方法，为解决的问题建立了充分的条件。通过解决凸优化问题，可以获得期望的估计器增益。最后，通过两个说明性示例来说明所开发方法的正确性和可用性。
