摘　　要：研究一种基于观测器的具有拒绝服务攻击的非线性网络控制系统的控制问题。为了能够抵抗非周期拒绝服务干扰攻击和节省网络通信资源,设计一种新的事件驱动控制策略,并计算出系统性能损失的最大值。首先,在利用T-S模糊方法建模时,建立一种模糊且具有网络时滞的控制系统模型;其次,通过Lyapunov稳定性理论,获得系统稳定的充分条件,同时给出事件驱动参数和观测器及控制器增益矩阵的设计方法;最后,通过卡车拖车系统的安全控制算例对结果进行验证。This paper mainly studies observer-based control problem for a class of nonlinear networked control systems with Denial of Server attacks.In order to resist aperiodic Denial of Server interference attacks and save network communication resources,a new event-triggered control strategy is designed based on the assumption that Denial of Server attacks are frequency interference and bandwidth consumption of the network,and the maximum value of system performance loss is also calculated.By using the T-S fuzzy method,a fuzzy control system model with network delay is established.Then,sufficient conditions for the stability of systems are obtained by Lyapunov stability theory.At the same time,event-triggered parameters and the design method of the observer and controller gain matrices are given.Finally,the results of this paper are verified by a safety control example of truck trailer system.
