最近针对工业控制系统的网络攻击突显了防止未来的攻击在经济上扰乱工厂的关键，或者更关键的是，防止影响工厂安全。这项工作建立了一个非线性系统框架，用于理解过程和控制设计的网络攻击弹性，并通过对三个控制设计的分析，指出如何检查控制律的这一性质。一个化学过程的例子表明，用于防止网络攻击的控制方法似乎是直观的，但除非它们满足非线性系统对这一性质的描述的要求，否则它们不能恢复网络攻击。
Recent cyberattacks against industrial control systems highlight the criticality of preventing future attacks from disrupting plants economically or, more critically, from impacting plant safety. This work develops a nonlinear systems framework for understanding cyberattack-resilience of process and control designs and indicates through an analysis of three control designs how control laws can be inspected for this property. A chemical process example illustrates that control approaches intended for cyberattack prevention which seem intuitive are not cyberattack-resilient unless they meet the requirements of a nonlinear systems description of this property.
