摘要

从信息物理融合系统(CPS

cyber physical system)的设计理念来看，要求系统中的通信计算部分和被控制物理对象进行紧密耦合操作。遵照这种紧耦合操作原则，针对无线网络控制系统(WNCS

wireless networked control system)，提出一种紧耦合自适应模糊控制方法。模拟实验数据显示这种设计方法能根据实时的 NCS 紧迫度和网络的拥塞度有效地调整被控系统的采样周期及网络信道占用优先级，从而优化利用了有限的网络资源，改善了整个网络控制系统的性能。

Abstract

From cyber physical system perspective

tightly coupling the communications and computing aspects with physical dynamics is profound.This characteristic is investigated for wireless networked control systems (WNCS).Following the tight coupling principle of CPS

a tight coupling adaptive fuzzy controlling methodology for WNCS is proposed.Through simulation experiments

it is showed that proposed method could adaptively adjust the controlled system's sample period and network channel access priority according to its real time control urgency and the network traffic condition

so as to optimize network utilization and improve the performances of the whole NCS.
