摘　　要：针对信息物理系统的虚假数据注入、执行器受到攻击问题,提出系统执行器在受到常值虚假数据注入攻击与有界时变虚假数据注入攻击时的自适应补偿控制器设计方法。自适应补偿控制算法应用于虚假数据注入攻击中,所设计的自适应律具有收敛速度快、估计参数准确等优点。该补偿控制算法能够基本上补偿虚假数据注入攻击产生的影响,可以证明最终闭环系统的所有信号是有界的并且系统状态能够渐近收敛到0.仿真实例验证了状态反馈自适应补偿控制器的有效性。For the false data injection of cyber physical systems,a designing method of adaptive compensation controller is proposed,which is used for compensation control when the system executor suffers from constant false data injection attack and bounded time-varied false data injection attack.The application of adaptive compensation control algorithm to the false data injection attack shows that the designed adaptive law has the advantages of fast convergence speed and accurate parameter estimation.The compensation control algorithm can substantially compensate for the effects of false data injection attacks.It can be proven that all signals from the final closed-loop system are bounded and the state of the system can asymptotically converge to zero.Finally,the simulation examples are provided to verify the effectiveness of the state feedback adaptive compensation controller proposed in this paper.
