摘要

提出了一种基于模糊双线性观测器的非线性系统故障诊断设计方法。该非线性系统采用模糊双线性模型(FBM)进行建模。建立了残差发电机最大故障灵敏度和扰动鲁棒性的充分条件。这些条件用线性矩阵不等式(LMI)的形式给出。最后通过数值算例说明了所得结果的有效性。

Robust H∞ fault detection for fuzzy bilinear systems via unknown input observer
In this paper, a new method to design a fault diagnosis based on a Fuzzy Bilinear Observer (FBO) for nonlinear systems is proposed. The nonlinear system is modeled as a Fuzzy Bilinear Model (FBM). Sufficient conditions are established in order to maximize the fault sensitivity and perturbation robustness of the residual generator. These conditions are given in Linear Matrix Inequality (LMI) terms. A numerical example is given to illustrate the effectiveness of the given results.
