中文摘要 |
本文研究了线性连续时滞系统的鲁棒故障检测问题. 利用H_/H∞故障检测方法, 设计了故障检测观测器, 并给出了时滞依赖的故障检测观测器设计条件. 本文直接给出刻画有限频故障检测性能的线性矩阵不等式条件, 避免因引入加权函数而产生的不准确性. 最后, 仿真算例表明时滞依赖的有限频故障检测观测器可以取得比已有结果更好的故障检测性能. |
英文摘要 |
This paper is concerned with the robust fault detection (FD) problem for linear continuous time-delay systems. Using H_/H-infinity fault detection techniques, we design the fault detection observer and give the design conditions for the delay dependent FD observer. We provide linear matrix inequality conditions for finite frequency FD performance, and avoid the approximations associated with frequency weights. An example is given to show that, in comparison with existing results, the proposed delay-dependent FD observer can achieve better FD performance. |
