The problem of resilient control of linear cyber-physical systems with cyber-attacked sensor measurements and actuator commands is studied in this article. Online reconstruction of unknown cyber-attacks is accomplished by an adaptive sliding mode observer with a novel injection term in the form of a dynamically extended equivalent control. Then, the attacked/corrupted sensor's measurements and the actuators are proposed to be cleaned up using the reconstructed attacks. The performance of the system prior to the attacks is shown to be retained after a transient response required for the attack reconstruction/estimation. The efficacy of the proposed algorithms is validated on an electrical power network.

自适应滑模观测器驱动的传感器和执行器攻击下信息物理系统的弹性控制

本文研究了具有网络攻击传感器测量和执行器命令的线性信息物理系统的弹性控制问题。未知网络攻击的在线重建是通过自适应滑模观测器完成的，该观测器具有动态扩展等效控制形式的新注入项。然后，建议使用重建的攻击来清理被攻击/损坏的传感器的测量值和执行器。攻击前系统的性能在攻击重建/估计所需的瞬态响应之后被保留。所提出算法的功效在电力网络上得到验证。
