本文研究了一类非线性网络控制系统的事件触发模糊滤波问题。将非线性网络控制系统建模为T - S模糊系统，并提出一种离散事件触发通信机制以减轻有限网络带宽的使用。采用逻辑零阶保持器来选择最新传输的数据包并丢弃乱序数据包。利用时滞系统方法——离散事件触发通信机制，将网络诱导时延和非线性系统统一为一个网络化的T - S模糊时滞系统。然后，基于一种互反凸方法为该系统推导出一个新的有界实引理。针对触发条件和模糊滤波器开发了一种新的协同设计方法，该方法保证相应的滤波误差系统在给定的干扰衰减水平下渐近稳定。最后给出两个例子以表明所提结果的有效性。版权归皇家所有（C）2015，由爱思唯尔出版集团出版。保留所有权利。
The problem of event-triggered fuzzy filtering is investigated for a class of nonlinear networked control systems in this paper. The nonlinear networked control system is modeled as a T-S fuzzy system and a discrete event-triggered communication scheme is proposed to mitigate the utility of limited network bandwidth. A logic zero order holder is employed to choose the latest transmitted data packet and discard the disordering packet. Using time-delay system method - the discrete event-triggered communication scheme, the network-induced delay and the nonlinear system are unified into a networked T-S fuzzy time-delay system. Then, a new bounded real lemma is derived for this system based on a reciprocally convex approach. A new co-design method is developed for the triggering condition and the fuzzy filter, which guarantees the correspondent filtering error system being asymptotically stable with a prescribed disturbance attenuation level. Finally two examples are given to show the effectiveness of the proposed results. Crown Copyright (C) 2015 Published by Elsevier B.V. All rights reserved.
