摘　　要：本文研究了在欺骗攻击下奇异马尔可夫跳变系统的状态感知事件触发H_(∞)-脉冲混杂反馈控制问题。为了进一步权衡控制性能和通信效率,提出了一种可根据当前系统状态自适应地调整事件触发阈值的基于周期采样的模态相关状态感知事件触发机制。基于所提出的事件触发机制,建立了一种模态相关的脉冲混杂反馈控制器。通过构造脉冲时间相关和马尔可夫跳变模态相关的Lyapunov-Krasovskii(L-K)泛函并结合奇异值分解技术,获得了奇异马尔可夫跳变系统在欺骗攻击下的H_(∞)随机容许性准则。在线性矩阵不等式框架下实现了状态感知事件触发器和H_(∞)-脉冲混杂反馈控制器协同设计。直流电机驱动负载的仿真实例验证了本文方法的有效性。This paper investigates state-sensitive event-triggered H_(∞)-impulse hybrid feedback control for singular Markovian jump systems under spoofing attacks.In order to further trade-off between control performance and communication efficiency,a modal-dependent state-sensitive event-triggered mechanism,which can adjust the event triggering threshold in real time according to the current system state,is proposed on the basis of periodic sampling.And based on the proposed event-triggered mechanism,a mode-dependent impulse hybrid feedback controller is established.The H_(∞)stochastic admissibility of singular Markovian jump systems under spoofing attacks is realized by constructing an impulse time-dependent and Markovian jump mode-dependent Lyapunov-Krasovskii(L-K)functional and exploiting singular value decomposition technique.The state-sensitive event-triggered mechanism and H_(∞)-impulse hybrid feedback controller co-design are realized via a set of linear matrix inequalities(LMIs).The simulation instance of DC motor driven load confirms the validity of the suggested methodology.
