摘要

针对一类离散非线性对象的跟踪问题，提出了一种自适应反馈控制方案。采用模糊逼近器对系统非线性进行自适应补偿。模糊逼近器的参数(包括非线性参数)采用了基于李雅普诺夫的设计。该方法采用一种特殊的逼近误差表达式、参数投影和带扇形的变结构控制来达到一致的最终有界性。

Adaptive fuzzy control for a class of discrete-time nonlinear systems

An adaptive feedback control scheme for the tracking of a class of discrete-time nonlinear plants is presented. A fuzzy approximator is used to adaptively compensate for the plant nonlinearities. The fuzzy approximator's parameters including nonlinear ones, are adapted using a Lyapunov-based design. The method uses a special approximation error expression, parameter projection, and variable structure control with a sector to achieve uniform ultimate boundedness.
