Design of an adaptive fuzzy sliding mode controller

Feng Zhang

Abstract

A new fuzzy sliding mode controller,combined with fuzzy adaptive control and sliding mode control,using linear feedback technology,is designed for reducing chattering in traditional sliding mode control systems.Based on fuzzy reasoning and the stability analysis of Lyapunov function,adaptive law of fuzzy control rules,which constitutes the fuzzy sliding mode controller,are derived.The controller provides effective solutions to problems in the traditional sliding mode control,such as the necessity to determine the parameter perturbation and external disturbance upper bound.The simulation results show the effectiveness of the method.
