摘　　要：本文研究了一类非线性时滞系统的H_∞故障检测观测器设计问题。以状态观测器作为残差产生器,建立观测误差动态系统。在系统的初始状态为不确定但有界的情形下,对这类观测器的设计提出两类改进的H_∞性能指标,并以线性矩阵不等式(LMI)形式给出了故障检测观测器的设计方法。The design problem of the H∞fault detection observer for a class of nonlinear delay systems is studied.A state observer is considered as the residual generator and the dynamic system of the observation error is constructed.Two improved H_∞performance indexes for such observer design are proposed under the assumption that the initial states of the system are uncertain but bounded. Design methods for fault detection observer are given in terms of linear matrix inequalities.
