摘要

摘要： 该文针对具有随机时延的网络控制系统故障诊断问题，分别进行Kalman滤波器和H1 滤波器的最优故障诊断滤波器设计. 通过迭代实现Kalman滤波器的故障诊断，在H1 滤波器设计中采用增广矩阵和线性矩阵不等式技术尽可能减小残差与故障之间的误差. 通过仿真验证了上述两种设计方法的有效性.

Abstract

Abstract: This paper discusses fault diagnosis for network control system with random delays. Two general fault detection filters are designed: Kalman filter and H1 filter. The former is obtained using an iteration method, and the latter is realized with linear matrix inequalities (LMI) and augmented matrices to ensure the smallest possible error between the residual and the fault. A numerical example is provided to show
effectiveness of the present methods.

Key words：  network control system; fault detection; Kalman filter; H1 filter
