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，研究模糊辨识器的稳定性和鲁棒性
For a class of nonlinear multivariable unknown dynamical systems, a fuzzy recognizer is proposed. IF-THEN inference rules are used in the design to construct multivariable fuzzy logic systems to realize the approximation of unknown functions in the system. Lyapunov synthesis and Singular perturbation theory, the stability and robustness of fuzzy recognizer
