说明：  预处理工具包括：主成分Analysi 小号（PCA），白化，过滤：高通滤波（HPF），低通滤波（LPF），子带滤波器（巴特沃斯，切比雪夫，椭圆）用的滤波器，频率子带和可调顺序子带的数量）或用户定义的 预处理功能。 后处理工具实际上包括：通过去除不想要的组件，噪声或伪像，对原始原始数据进行压缩和重建（“清理”）。 该算法不仅可以执行ICA，还可以执行二阶统计盲源分离（BSS），稀疏分量分析（SCA），非负矩阵分解（NMF），平滑分量分析（SmoCA），因子分析（FA）和任何其他可能的矩阵X = HS + N或 Y = WX形式的因式分解，其中H = W +是混合矩阵或基本向量矩阵。X是观测数据的矩阵，S是原始数据的矩阵，N表示其他噪声的矩阵。 ICA / BSS算法是纯数学公式，功能强大，但机械程序却很复杂：机械得到最佳实施后，用户要做的工作不多。ICALAB的成功和有效使用在很大程度上取决于先验知识，常识以及对预处理和后处理工具的适当使用。(icalab toolboxes for signal process, based on the software MATLAB.)

由于PSO工具箱较难开发出多目标优化，采用MATLAB编写程序，得出VPPSO的源代码，进行优化设计，效果不错，希望和大家一起学习，共同进步(The PSO toolbox more difficult to develop a multi-objective optimization using MATLAB program, to draw VPPSO the source code, optimized design, good results, and we hope that with learning and common progress)

A hardware-in-the-loop simulation of a wind energy conversion system is used to assess a MPPT strategy for different velocities. The actual system is composed of the blade, a mechanical power train, a squirrel cage induction generator and power electronics. The experimental set-up consists of a DC drive connected to the induction generator. The DC machine is controlled to impose the same behavior as the wind turbine to the induction generator. Fluctuations of wind velocity and non-linear characteristics of the turbine are taken into account. All numerous model and controls blocks are organized according to Energetic Macroscopic Representation for real-time implementation. A very simple MPPT strategy without wind velocity measurement is achieved using a look-up table. This strategy includes a rotation speed limitation. Experimental results are provided for weak and medium wind profiles.

首先定义累计量函数，然后通过调用四阶累计量来实现有色噪声中谐波恢复，但有个缺点是信号源估计在实际应用时应有所改进！(First, the definition of cumulant function, and then by calling the fourth-order cumulant to achieve the harmonic retrieval in colored noise, but one drawback is that the signal source is estimated that in practical applications should be improved!)
