摘　　要：针对一类单输入单输出不确定非线性系统 ,提出了一种稳定的自适应模糊控制方法。这种控制方法不需要系统状态可测的条件 ,而是通过设计模糊状态观测器来估计系统的状态。证明了所提出的控制方法不但能使闭环系统稳定 。A stable fuzzy adaptive control method for the first class single input/output non linear non identified system is presented in which the system status is estimated through the design of a fuzzy observer, rather than by the traditional measurable conditions. It is proved that the new method given in this paper not only makes the closed loop system stable but also is characterized by the output error being capable controlled.
