【摘要】 网络控制系统(Networked control systems,NCSs)是反馈通过数据网络的控制系统,跟传统控制系统相比,具有很多优点。但是,网络包含的时滞和其他数据特性会使得设计时未考虑网络的反馈系统性能下降。本文总结了近年来一些关于网络控制系统故障诊断的主要思想和结果,包括具有时滞的网络控制系统的故障检测及诊断技术,基于简单时滞系统模型;Markovian跳跃系统模型,混合系统模型及T-S模型的网络控制系统;以及对今后研究的展望。更多还原

【Abstract】 Networked control systems(NCSs) are feedback systems closed through data networks.NCSs have many advantages compared with traditional systems;however,the network-included delay and other characteristics of data networks can degrade the performance of feedback systems without considering the network.During recent years,the problems of fault diagnosis for NCSs are investigated.This paper summarizes some main ideas and results on the fault diagnosis of NCSs,including the fundamentals of fault detection and diagnosis approaches based on the simplified time-delay system models,the Markovian jump model,hybrid model,T-S model;and the perspectives of future research for NCSs.更多还原
