The problem of robust fault estimation (FE) for a class of nonlinear systems in discrete-time domain is studied via proposing a comprehensive partition-based switching scheme. Both enhancement factors and attenuation factors are designed synchronously for accomplishing a comprehensive partition of the entire space spanned by the considered normalized fuzzy weighting functions. Thanks to the proposed comprehensive partition-based switching scheme, six subspaces would be obtained by identifying the real-time permutation order of the underlying parameters. Therefore, a novel fuzzy FE observer with six kinds of switching modes can be on-line implemented. As a result, the robust H∞ performance index can be enhanced since much more information is employed than those reported results. Finally, simulation comparisons over the existing results are provided to show the obtained advantages of the article.

通过基于分区的综合切换方案对离散时间非线性设备进行鲁棒故障估计

通过提出一种基于分区的综合切换方案，研究了离散时域中一类非线性系统的鲁棒故障估计（FE）问题。增强因子和衰减因子都是同步设计的，以完成对所考虑的归一化模糊加权函数跨越的整个空间的综合划分。由于提出了基于分区的综合切换方案，通过识别基础参数的实时排列顺序，将获得六个子空间。因此，可以在线实现一种具有六种切换模式的新型模糊有限元观测器。因此，可以增强稳健的 H∞ 性能指标，因为使用了比报告结果多得多的信息。最后，
