网络攻击严重威胁着网络物理系统的安全。已经研究了弹性控制以防御网络攻击。然而，现有的弹性控制方案没有考虑致动器攻击引起的系统结构变化。这种结构的变化是更具破坏性和有害的比文献中研究的致动器攻击的情况下，需要新的弹性控制策略。本文将在云计算环境中解决这些问题，云计算环境越来越多地部署在大规模CPS中。更具体地说，弹性控制方案的设计，其中包括两个控制器：本地弹性控制器和基于云的弹性控制器。本地弹性控制器承受致动器的攻击，简单地篡改致动器的输出在很大程度上。基于云的弹性控制器旨在抵抗破坏系统结构的执行器攻击。在永磁同步电动机控制系统上进行了仿真，以证明所提出的弹性控制方案。
Cyber attacks threaten the security of cyber-physical systems (CPSs) seriously. Resilient control has been studied to defend cyber attacks. However, existing resilient control schemes have not considered system structure changes caused by actuator attacks. Such structure changes are more destructive and harmful than the actuator attack scenarios investigated in the literature, demanding new resilient control strategies. They will be addressed in this article in cloud computing environments, which are increasingly deployed in large-scale CPSs. More specifically, a resilient control scheme is designed which consists of two controllers: a local resilient controller and cloud-based resilient controller. The local resilient controller withstands actuator attacks that simply tampers the actuator output to a large extent. The cloud-based resilient controller aims to resist the actuator attacks that destroy the system structure. Simulations are conducted on a permanent synchronous motor control system to demonstrate the proposed resilient control scheme.
