摘　　要：对一类非线性多变量未知动态系统，提出一种模糊辨识器，设计中采用ＩＦ—ＴＨＥＮ推理规则来构造多变量模糊逻辑系统，实现对系统中未知函数的逼近；应用李亚普诺夫合成方法和奇异摄动理论。A robust fuzzy identifier for a class of unknown multivariable nonlinear systems is presented. “IF-Then” inference rules are used to construct fuzzy logic system, and approximate the unknown functions in the systems. Based on the Lyapunov synthesis method and singular perturbation theory, the stability and robustness of the fuzzy identifier are discussed.
