提出一种新的时滞分解方法-时滞不等分法，研究了T-S模糊常时滞系统的稳定性准则问题。基于Lyapunov稳定性理论，构造恰当的Lyapunov-Krasovskii泛函，以线性矩阵不等式形式给出一个决策变量少、运算效率高、保守性小的时滞相关稳定性准则。最后给出数例说明该方法的有效性。

In this paper , a new delay decomposition approach is proposed , which is unequal delay decomposition approach .The problem of stability criterion for T-S fuzzy systems with constant time delay is concerned.Based on Lyapunov stability theory , it constructs an appropriate Lyapunov-Krasovskii functional . A less conservative delay-dependent stability criterion with less decision variables and more computing efficiency is formulated in form of linear matrix inequalities .Finally , numerical examples are provided to show the effectiveness of the proposed method .
