摘要
研究拒绝服务(denial-of-service,DoS)攻击下的n阶受扰系统基于幂次趋近律的滑模控制.首先,通过构造状态预测器重建攻击活跃期间丢失的系统状态,基于预测器状态和非光滑函数,设计能量受限型DoS攻击情况下的幂次趋近律滑模控制器,进一步分析保持系统稳定性的充分条件;其次,当系统存在外部干扰情况下,证明幂次趋近律滑模控制方法仍能保持非光滑控制器的强抗干扰能力;最后,通过数值仿真对所提出的理论证明结果进行验证.
In this paper,sliding mode control based on power reaching law for an n-order disturbance system under denial-of-service(DoS)attacks is studied.First,the states predictor is constructed to reconstruct the system states lost during the active periods of attacks.Based on the predictor states and non-smooth function,a power reaching law sliding mode controller under energy constrained DoS attacks is designed,and the sufficient conditions for the stability of the system are further analyzed.Then,it is proved that the power reaching law sliding mode control method still maintains the strong anti-interference ability of the non-smooth controller when the system has external disturbance.Finally,the results of the theoretical proof are verified by numerical simulation.
