摘要
考虑了区间时变时滞模糊系统的稳定性问题。利用T-S模糊模型对模糊系统进行了研究,利用线性矩阵不等式的形式给出了此类模糊系统在时滞相关意义下保守性更小的稳定性判据。由于加入了自由矩阵,所得结果保守性更小。并且给出了一个数值例子说明了所得稳定性判据的有效性。
This paper is concerned with the problem of the stability of fuzzy systems with interval time-varying delay. The Takagi-Sugeno （T-S） fuzzy model is introduced to approximate the fuzzy systems. A less conservative delay-dependent stability criterion of fuzzy systems is given in the form of linear matrix inequalities. Some free-weighting matrices are introduced to get a less conservative stability criterion. A numerical example is also given to show the effectiveness of the proposed stability criterion.
