摘　　要：研究具有多通道数据传输的飞行器网络控制系统故障检测滤波器(FDF)设计问题.考虑每个通道存在各自的网络时延,且丢包符合Markov随机过程.首先,将系统建模为转移概率部分已知的离散Markov跳变线性系统,并设计了基于观测器的故障检测滤波器,将故障检测问题转化为H∞滤波问题;然后,利用LMI工具给出了FDF的可解条件和求解方法;最后,通过某飞行器网络控制系统的数值仿真实验验证了所提出方法的有效性.The fault detection filter（FDF） design problem for a class of networked flight control systems with multiple channels data transmission is studied. Considering the network-induced delay and packet dropouts of each channel, discrete-time Markov jump linear system model with partly known transition probabilities is established. Based on the obtained model, observer-based FDF is designed. Then the addressed fault detection problem is converted into a problem of？？∞filtering. Sufficient conditions to guarantee the existence of the FDF and solutions of this problem are simultaneity derived. Finally, a simulation experiment on a networked flight control system validates the effectiveness of the proposed method.
