Abstract

This paper deals with the fault detection problem for a class of discrete-time networked systems with random delays and disturbance. With the maximum allowable delay, a binary stochastic switching sequence is used to simplify the FDI for NCS. Attention is focused on the design of a fault detection filter, which can be robust for the unknown disturbance. A sufficient condition for the existence of the desired fault detection filter is established in terms of a linear matrix inequality (LMI). A numerical example is provided to illustrate the feasibility and applicability of the proposed techniques.
随机时延网络控制系统的故障检测
研究了一类具有随机时滞和扰动的离散网络系统的故障检测问题。在允许的最大时延下,采用二元随机切换序列来简化NCS的FDI。重点研究了故障检测滤波器的设计,使其对未知干扰具有较强的鲁棒性。利用线性矩阵不等式(LMI)建立了期望故障检测滤波器存在的充分条件。通过数值算例说明了所提方法的可行性和适用性。
