Abstract

A fuzzy approximation-based adaptive tracking control scheme is proposed for a class of multiinput-multioutput (MIMO) nonlinear systems with multiple time delays.Fuzzy T-S model-based adaptive time-delay fuzzy logic systems are developed to approximate the unknown nonlinear time delay functions.Thus

the modeling to nonlinear systems is implemented.The update laws for parameters of the fuzzy logic systems are derived by the tracking error.

∞

compensator is designed to eliminate fuzzy approximation errors and external disturbances.Based on Lyapunov stability theorem

the proposed control scheme can guarantee the stability of the closed loop systems and obtain anticipant

tracking performance

as well.Simulation results of the manipulator demonstrate the effectiveness of the control scheme.
