摘要: 针对一类非线性系统提出一种利用观测器原理来求解干扰抑制项和控制器参数的新 型模糊自适应控制方法.通过寻求线性矩阵不等式(LMI)的可行解来得到具有H∞跟踪性能的 模糊自适应观测器.并证明了如果该观测器具有H∞跟踪性能,则由该观测器参数构成的控制 器,可以保证闭环系统稳定.Abstract: A new adaptive fuzzy law is proposed based on the principle of observer for a class of nonlinear system. The fuzzy adaptive observer with H∞ tracking performance is designed through seeking the feasible solutions of a linear matrix inequality (LMI). And it is proved that the controller based on the parameters of observer with H∞ tracking performance will stabilize the close loop system.
