摘　　要：针对混合网络攻击环境下的信息物理系统,研究了基于输出反馈的预测补偿控制问题,提出了具有多步预测的补偿控制方法.首先,考虑到混合攻击特性和攻击能量受限等因素,建立了具有嵌套子系统结构的信息物理系统切换模型;其次,借助李雅普诺夫稳定性理论和线性矩阵不等式技术给出了系统指数稳定的充分条件,在此基础上设计了基于输出反馈的预测补偿控制策略,实现了信息物理系统的镇定控制;最后,通过网络化直流电机控制系统仿真实例验证了所提控制方法的正确性和有效性.The predictive compensation control problem is investigated based on output feedback for cyber-physical systems(CPS)under hybrid cyber attacks.A compensation control method with multi-step prediction is proposed.Firstly,according to the characteristics of hybrid cyber attacks and attack energy constraints,a switching system model of CPS with an embedded subsystem structure is established.Secondly,sufficient conditions for the exponential stability of the systems are derived by utilizing Lyapunov stability theory and linear matrix inequality technology.Then an output feedback-based predictive compensation control strategy is presented to achieve stabilization control of CPS.Finally,a simulation example of a networked DC motor system is provided to demonstrate the correctness and effectiveness of the proposed method.
