Robust H_∞ filtering for uncertain nonlinear neutral delay systems

研究了带有范数有界的参数不确定性的非线性中立型时滞系统的鲁棒H∞滤波器问题。引入单侧Lipschitz条件来估计非线性向量函数对滤波器的影响。将所设计的鲁棒H∞滤波器用线性矩阵不等式表示。

This paper deals with the problem of robust H~ filtering for a class of nonlinear neutral delay systems with norm-bounded parameter uncertainties appearing in all the matrices of the linear part of the system model. The one-sided Lipschitz condition is introduced to estimate the influence of nonlinear vector functions on the filter. A linear matrix inequalities （ LMIs ） approach is proposed to design a robust H∞ filter such that the resulting system is robustly stable.
