一类MIMO非线性系统的自适应模糊控制

Adaptive Fuzzy Contol over a Class of MIMO Nonlinear systems

本文针对一类MIMO非线性系统提出了模糊自适应控制方法,用FLS矩阵来逼近未知函数阵,用指数饱和函数项对逼近误差进行补偿.该方法不但能保证闭环系统稳定,而且使跟踪误差收敛于原点的小邻域内.

A fuzzy control method for a class of MIMO Nonlinear systems is Presented. By this method,fuzzy logic systems matrices are used to approximate unknown function matrices,exponential saturation function term is employed to compensate for approximate errors. It proues that the proposed method can not only guarantee the stability of this closed-loop system,but also narrow the tracking error converge to small neighbor hood of orgin.
