【摘要】 研究了一类不确定线性时滞系统鲁棒故障诊断滤波器的设计问题.将基于状态观测器的故障诊断滤波器作为残差产生器,应用H_∞理论将鲁棒故障诊断滤波器的设计问题转换为模型匹配问题.推导并证明了问题可解的充分条件,给出了一种鲁棒故障诊断滤波器设计的LMI方法.算例验证了该方法的有效性.更多还原

【Abstract】 Studied the robust fault detection filter design problem for a class of uncertain linear time delay sys- tems.An observer-based fault detection filter is considered as residual generator.By using H_∞ theory,the ro- bust fault detection filter design problem is formulated as a model-matching problem.A sufficient condition and further the solution of RFDF are derived in the terms of matrix inequalities.A numerical example is given to il- lustrate the effectiveness of the proposed approach.更多还原
