摘　　要：针对虚假数据注入攻击下信息物理系统的安全控制问题,提出两种滑模控制设计方法。利用异常检测机制的阈值信息获取虚假数据注入攻击的上界信息,并应用获得的攻击上界信息构造鲁棒滑模控制方法。采用自适应技术估计攻击模式的上界信息,进而结合攻击模式的估计上界信息设计自适应滑模控制方法。然后,稳定性理论分别证明了两种控制方法下动态系统的安全稳定性。最后,仿真结果表明,在虚假数据注入攻击的情况下,所设计的鲁棒及自适应滑模控制方法能确保信息物理系统稳定并具有较好的鲁棒性能。Two kinds of sliding mode control design methods are proposed for the security control problem of cyber-physical systems under the false data injection attack.Firstly,the threshold information of anomaly detection mechanism was used to obtain the upper bound information of the false data injection attack,and the obtained upper bound information was used to construct a robust sliding mode control method.Then,an adaptive technique was used to estimate the upper bound information of the attack mode,and an adaptive sliding mode control method was designed by the combination of the estimated upper bound information of the attack mode.In addition,the security and stability of the dynamical system under two kinds of control methods were proved based on stability theory.Finally,the simulation results show that the designed robust and adaptive sliding mode control methods can ensure the stability of cyber-physical systems and have good robust performance under the false data injection attack.
