简介:针对短时延情况,本文利用容错的思想建立了SISO(Single-InputSingle-Output)网络控制系统发生传感器故障时的模型。在此基础上,借助切换系统理论分析了闭环网络控制系统的稳定性。用LMI形式给出了系统渐近稳定的充分条件和控制器的设计形式,最后给出了仿真证明。
简介:随着计算机技术网络技术的发展,特别是互联网及社会公共网络平台的快速发展,在"两化"融合的行业发展需求下,DCS系统广泛应用于各类行业。由于DCS工业控制系统在初建设时更多的是考虑各自系统的可用性,并没有考虑系统之间互联互通的安全风险和防护建设,造成病毒、木马等安全威胁向工控领域迅速扩散。为了简要介绍目前工控系统的安全问题,本文首先从DCS工业控制系统的定义和三层结构出发,引出了DCS工控系统的安全问题,阐述了该安全问题的分布特点。然后从技术角度,就攻击者与攻击途径、网络攻击的检测与响应、系统安全建模与脆弱性分析等多个重要问题进行了详细的讨论。最后,提出了纵深防御的安全理念,并以此为指导,构建了由边界系统、防御系统、防卫系统等三部分组成的综合防御体系,旨在为工业控制系统提供全方位、多层次、完整生命周期的保护。
