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模糊建模,在此基础上研究基于观测器的模糊动态输出反馈控制,利用矩阵不等式(LMI)算法给出了模糊闭环系统稳定的充分条件及其反馈控制增益和观测器增益的求法,以及输出反馈控制器的设计方法。最后仿真结果证明所提出的控制方法是有效的。 A class of uncertain nonlinear systems is modeled by fuzzy T-S model.A fuzzy state feedback controller and robust observer are designed.Based on algorithm of linear matrix inequalities, the sufficiency of fuzzy closed loop system, feedback gain matrix and observer gain matrix algorithms are given.Also the way how to design the output feedback controller is given.
