摘要
讨论了T-S模糊系统的二次稳定性问题.得到了两个等价的基于线性矩阵不等式(Linear matrix inequality,LMI)和Sum-of- squares(SOS)的充分条件.无论是在理论上,还是在数值示例方面,都表明文中结论放宽了已有的相关方面的结论,降低了此类问题判别条件的保守性.
This paper considers the stability of T-S fuzzy systems. Two equvilent sufficient conditions, represented in terms of linear matrix inequaiity(LMI) and Sum-of-squares (SOS), are obtained. The theorems presented in this paper have less conservatism than the existing ones, as have been verified by both theoretic analysis and numerical example.
