蛙跳积分法数值模拟Duffing方程和单摆运动的matlab程序(Numerical simulation leapfrog integration Duffing equation and pendulum motion)

这个文件实现了Matlab/Simulink中的三维查找表，对要用到查表的人有帮助，里面用到Reshape函数(This file implements the Matlab/Simulink in a three-dimensional look-up table for use to help people look-up table, which used Reshape function)

该程序可用于近红外光谱二阶求导预处理，经本人实测，程序可用。(The program can be used near-infrared spectroscopy second derivative pretreatment, as I found, the program is available.)

This paper presents a fuzzy tuning approach to sliding mode control for tracking-performance enhancement in a class of nonlinear systems. The sliding surface can rotate or shift in the phase space in such a direction that the tracking behaviour can be improved. It is shown that with arbitrary initial conditions, the reaching time and tracking error in the approaching phase can be signi辌antly reduced. Chattering can also be reduced by fuzzy tuning of the controller parameters
