研究了具有状态时滞的连续时间切换系统的鲁棒故障检测问题。根据系统模式，故障检测滤波器用作残差发生器。注意力集中在设计的过滤器，这样，对于建模误差，未知的输入和控制，残差和故障之间的误差最小化。所解决的故障检测滤波器的设计转换成一个辅助H？过滤问题。利用Lyapunov-Krasovskii泛函方法和平均停留时间方法，以线性矩阵不等式的形式给出了该问题可解的充分条件.最后通过两个算例验证了该方法的有效性。
This study addresses the robust fault detection problem for continuous-time switched systems with state delays. The fault detection filter is used as the residual generator depending on the system mode. Attention is focused on designing the filter such that, for the modelling errors, the unknown inputs and the control one, the error between the residuals and the faults is minimised. The addressed fault detection filter design is converted into an auxiliary H ? filtering problem. By using the Lyapunov-Krasovskii functional method and average dwell time approach, a sufficient condition for the solvability of this problem is established in terms of linear matrix inequalities (LMIs). Two examples are provided to demonstrate the effectiveness of the proposed method.
