使用matlab设计PID控制器消除系统静态速度误差的方法，主要使用等幅振荡法,并通过WORD给出了传递函数。(PID controller design using matlab static speed error elimination systems approach, the main use of the oscillation amplitude France, and through the WORD gives the transfer function.)

智能控制第二版刘金琨著。 本书较全面地叙述了智能控制的基本理论、方法和应用。此代码为次数的附带程序。(Intelligent Control Second Edition was written by Liu Jin_Kun. This book describes more fully the intelligent control of the basic theory, methods and applications. This code is the number of accompanying program.)

这个函数的功能主要是用来求样本点到蕨类中心的距离(find the distencebetween the sample and cluster)

1、 降噪步骤： （1） 一维信号的小波分解。选择一个小波并确定分解的层次，然后进行分解运算。 （2） 小波分解高频系数的阈值量化。对各个分解尺度下得高频系数选择阈值进行软阈值量化处理。 （3） 一维小波重构。根据小波分解的最底层低频系数和各高频系数进行一维小波重构。 matlab里面有关于去噪的函数，你可以找一下~~ 这说的只是基本原理，希望有所帮助(1, noise reduction steps: (1) one-dimensional signal wavelet decomposition. Select a wavelet decomposition level and determining, and then divide the operation. (2) high coefficient wavelet thresholding. For each decomposition scales have high coefficient selection threshold soft threshold quantization. (3) one-dimensional wavelet reconstruction. According to the lowest level of the low frequency wavelet coefficients and high frequency coefficients of each one-dimensional wavelet reconstruction. There are about denoising matlab function, you can find some ~ ~ This says just the basic principle, we hope to help)
