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.Abstract: This paper considers the stability of T-S fuzzy systems. Two equvilent sufficient conditions, represented in terms of linear matrix inequality(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.
