Robust fault diagnosis for singular nonlinear systems with distributed delays

研究了用Takagi-Sugeno模糊模型描述的带分布时滞奇异非线性系统的鲁棒故障诊断问题。设计基于模糊滤波器的残差产生器,将问题归结为H∞滤波,给出了奇异时滞模糊系统鲁棒H∞故障诊断滤波器存在的充分条件及线性矩阵不等式求解方法。

This paper considers the robust fault diagnosis problem for singular nonlinear systems with distributed delays described by Takagi-Sugeno(TS) fuzzy models.A residual generator based on a fuzzy filter was designed and the problem was converted to H∞ filtering.Sufficient conditions are given to guarantee the existence of H∞ fault diagnosis filter for singular time-delay fuzzy systems.The linear matrix inequality(LMI) method to design the fault diagnosis filter is also given.
