双馈低穿

说明：  2019年数学建模大赛题目,B题的题目，注意是研究生数学建模大赛(Mathematical Modeling Competition)

基于改进的PI模型对非线性曲线进行拟合，二次寻优算法进行参数辨识，用逆模型前馈补偿(classical PI modeling)

说明：  在原始正弦信号中加入线频干扰，后通过自适应陷波器输出，最后计算信号误差，程序可直接出图并有详细注释(The line frequency interference is added to the original sinusoidal signal, and then output by adaptive notch filter. Finally, the signal error is calculated. The program can be directly plotted with detailed notes)

说明：  python读取csv 文件，提供了神经网络的程序，以及自编码器(Python reading CSV file)

说明：  采用快速固定点法求解ICA，进行主成分分析(ICA was solved by fast fixed point method and principal component analysis was performed)

转载供大家学习讨论，共同提高！我很喜欢搞程序编程，但是刚进入这领域，还在处于学习-reproduced for your study and discussion, common in! I like engaging programming, but just entering this field, but also in learning
