【摘要】 研究受L2有界未知输入影响的一类奇异Markov跳跃系统的鲁棒故障检测问题。采用基于观测器的故障检测滤波器(FDF)作为残差产生器,将故障检测滤波器的设计归结为随机意义下的H∞滤波问题。推导并证明了问题可解的充分条件,并通过求解线性矩阵不等式得到了故障检测滤波器参数矩阵的解。算例验证了所给算法的有效性。更多还原

【Abstract】 This paper deals with the problem of robust fault detection for a class of singular Markovian jump systems with L2 norm bounded unknown input.Using an observer-based fault detection filter(FDF)as a residual generator,the design of robust FDF is formulated in the framework of stochastic H∞ filtering.Sufficient conditions on the existence of FDF and parameter matrices to the FDF are derived in terms of linear matrix inequalities(LMI).A numerical example is given to illustrate the effectiveness of the proposed method.更多还原
