摘要 利用模糊 T- S模型对一类不确定非线性时滞系统进行建模 ;在此基础上 ,提出了模糊不确定时滞系统的状态反馈控制及其输出反馈控制的设计 ,并给出了模糊闭环系统渐近稳定的充分条件 ;基于李亚普诺夫函数和线性矩阵不等式方法 ,证明了模糊系统的渐近稳定性。 Theproblemoffuzzy2modelingfor uncertain time-delay nonlinear systems by fuzzy T-S model is addressed. On the basis of the fuzzy modeling, fuzzy feedback control and output feedback control are developed. Sufficient conditions are derived for robust stabilization in the sense of Lyapunov asymptoticstabilityandformulatedin the form of linear matrix inequalities (LMIs), which can be efficiently solved with LMI optimization techniques.
