针对存在马尔可夫短时延和丢包的网络环境,研究了飞行器网络控制系统的故障检测系统设计与优化问题.将含有上述问题的网络化控制系统建模为离散的马尔可夫跳变系统.在此基础上,基于观测器构建残差生成器,将故障检测问题转换成H∞滤波问题,以LMI(Linear Matrix Inequality)的形式得到并证明了故障检测滤波器存在的充分条件和求解方法.为进一步改善检测性能,提高检测系统对故障信号的灵敏度,采用一种时域优化方法对残差评估函数进行优化处理,并给出了该优化问题最优解的求解方法.数值仿真说明了所提方法的有效性. Aiming at the network environment with Markov short delay and packet loss, the design and optimization of fault detection system for aircraft network control system are studied. The networked control system with the above problems is modeled as discrete Markov transition system Based on this, the residual generator based on observer is constructed, and the problem of fault detection is converted into H∞filtering problem. The sufficient condition and solution to the existence of fault detection filter are obtained and proved in the form of LMI (Linear Matrix Inequality) In order to further improve the detection performance and improve the sensitivity of the detection system to the fault signals, a time domain optimization method is adopted to optimize the residual evaluation function and the solution to the optimal solution of the optimization problem is given. Numerical simulation shows that The effectiveness of the proposed method.
