一类非线性系统的H_∞观测器的设计方法

A Design Approach of H_∞ Observer for a Class of Nonlinear Systems

研究了一类非线性系统(T-S模糊系统)的H∞观测器设计问题。在对象初始状态不确定情形下,提出一个改进的H∞性能指标,并以线性矩阵不等式(LMI)形式给出了观测器设计方法。

The H∞ observer design problem for a class of nonlinear systems （ T-S fuzzy systems） is considered. An improved H∞ performance index is proposed when the plant initial state is uncertain. A design approach of the observer is given in terms of linear matrix inequalities.
