说明：  小波信号去噪例子,默认阈值去噪，强制去噪和软阈值去噪三种方法(wavelate-wavedec)

车流量预测 ，采用MATLAB进行编写。(Traffic flow forecasting, using MATLAB to write.)

用simulink搭建的自抗扰控制器的非线性反馈模型，与之前传的那个略有不同(Simulink build the ADRC controller of nonlinear feedback model is slightly different, and that before the transfer)

加入重复控制，WgUnizA参数使用matlab实现智能预测控制算法，是国外的成品模型，基于互功率谱的时延估计，nfJZEzi条件最小均方误差（MMSE）的算法，包含光伏电池模块、MPPT模块、BOOST模块、逆变模块。( Join repetitive control, WgUnizA parameter Use matlab intelligent predictive control algorithm, Foreign model is finished, Based on the time delay estimation of power spectrum, nfJZEzi condition Minimum mean square error (MMSE) algorithm, PV modules contain, MPPT module, BOOST module, inverter module.)

信号的相关性是信号本身很重要的性质，本程序就是求随机信号的自相关性。(Signal is the relevance of the signal itself is very important properties, this procedure is for the random signals between autocorrelation. )

该程序主要针对机械等信号进行低通滤波。内包含了一个例子，并对巴特沃思滤波器的主要设计函数进行了详细的说明。(The program mainly for machinery, low-pass filtered signal. Contains an example, and the Butterworth filter is designed primarily for a detailed description of the function.)

利用matlab7进行系统建模与仿真的例子(Modeling and Simulation using matlab7)

压缩包里面有四个程序：在matlab中对图像进行过滤操作和频率操作，和函数的变换(Compressed inside four programs: the transformation of image filtering operation and the frequency of operation, and function in matlab)

说明：  遗传算法（Genetic Algorithm）是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型，是一种通过模拟自然进化过程搜索最优解的方法，它最初由美国Michigan大学J.Holland教授于1975年首先提出来的，并出版了颇有影响的专著《Adaptation in Natural and Artificial Systems》，GA这个名称才逐渐为人所知，J.Holland教授所提出的GA通常为简单遗传算法（SGA）。(a genetic algorithm (GA) is a search heuristic that mimics the process of natural evolution. This heuristic is routinely used to generate useful solutions to optimization and search problems. Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover.)

L-DE是一个“几何”差分演化差异,其行为不根据坐标系统。(L-DE is a "geometrical" Differential Evolution variant, whose behaviour is not depending on the coordinate system. )
