摘要

本文研究受有界不确定性影响的非线性系统的模糊建模问题。该模型由两部分组成:线性不确定部分和非线性部分。通过对部分工作点进行线性化，得到系统的线性不确定部分。采用下降梯度法对非线性零件参数进行估计。最后，通过两个算例说明了所提建模方法的有效性。

On the fuzzy modeling of uncertain nonlinear systems

This paper deals with fuzzy modeling of nonlinear systems affected by bounded uncertainties. The proposed model is composed of two parts: a linear uncertain part and a nonlinear part. The linear uncertain part is obtained by system linearization around some operating points. Nonlinear part parameters are estimated through the use of the descent gradient method. Finally, two examples are treated to illustrate the effectiveness of the proposed modeling method.
