在集中式网络控制系统（NCS）中，代理与中央处理单元共享本地数据，中央处理单元为代理生成控制命令。NCS中的控制中心通过通信网络接收来自代理的信息，并为代理产生控制命令。尽管NCS具有所有优点，例如降低设计成本和简单性，但网络连接的集成可能会使NCS暴露于对抗性攻击，例如虚假数据注入（FDI）。本文针对永磁直线电机网络化系统，提出了一种新的控制方法，以减轻FDI攻击的影响，保证控制目标的实现。为了实现这一点，非奇异终端滑模控制将设计使用一个观察器，以确保跟踪目标。扩展状态观测器将估计系统的状态，并估计FDI攻击的真实的时间。控制中心将产生对FDI攻击和任何干扰具有鲁棒性的控制信号。一个基于李雅普诺夫稳定性分析将被用来证明的稳定性的神经网络控制器。通过对一个三智能体永磁直线电机网络的仿真，验证了所提方案的有效性。
In a centralized Networked Control System (NCS), agents share local data with the central processing unit that generates control commands for agents. The control center in an NCS receives information from the agents through a communication network and produces control commands for agents. Despite all of the advantages of an NCS, such as reduced design cost and simplicity, the integration of networked connectivity can expose the NCS to adversarial attacks, such as false data injection (FDI). In this paper, a novel control approach will be developed to mitigate the FDI attack’s effect and guarantee the control objective in a networked system of permanent magnet linear motors. To achieve this, a non-singular terminal sliding mode control will be designed using an observer to ensure the tracking objective. The extended state observer will estimate the state of the system and estimate the FDI attack in real time. The control center will produce a control signal which is robust to the FDI attack and any disturbance. A Lyapunov-based stability analysis will be used to prove the stability of the observer-based controller. A three-agent permanent magnet linear motor network is selected for the simulation to show the effectiveness of the proposed scheme.
