熵（近似熵，样本熵）,适合初学者。值得一看。。。。。(Entropy (entropy of approximate entropy, sample), suitable for beginners. Worth a look... )

GALGORITHM OPTIMZATION TECHNIQUE

实现增量调制的简单的程序，十分简短。你应该可以作得更好(delta modulation to achieve the simple procedure is very short. You should be able to do better)

实现微电网逆变器的平滑切换PQ和VF之间切换，供参考学习交流用(o achieve smooth switching between microgrid inverters PQ and VF switching, for reference, learning and communication.)

针对电压暂降的问题,按照“DVR系统设计→检测算法研究→控制方法研究→系统建模→结果分析→硬件实现”的思路,利用参数模糊自整定PID控制方法,对三相无串联变压器型DVR进行控制,实现了对系统电压暂降快速、准确的补偿。(Aiming at the problem of sags, a fuzzy PID control strategy is proposed to the transformerless DVR following the idea of “DVR system→detection algorithm→control strategies→system modeling→results analysis→hardware implementing”. )

说明：  四旋翼控制PID，轨迹定位，matlab编程(using matlab, PID control, tracking)

这个程序再matlab2012b版本上调试成功，以前在毕业设计的时候在网上找到的资料，希望对大家有用，SOM算法,matlab程序,是经典的教科书的例子程序(This program debug version then matlab2012b success in graduate design information previously found on the Internet when we want to be useful, SOM algorithm, matlab program, is a classic textbook example of program)

HILBERT_MATLAB的介绍和简单运用(HILBERT_MATLAB introduction and simple to use)

说明：  基于负熵的盲源分离算法，可以用于语音的盲分离，提高语音信号质量。本代码中，对原始信号分别为正弦波，方波，和随机信号，通过高斯信道的混合矩阵，获得接收信号，并通过基于负熵的盲源分离算法分理处原始信号。PS：Matlab版本为2018Ra(The blind source separation algorithm based on negative entropy can be used for speech blind separation and improve the quality of speech signal. In this code, for the original signal, sine wave, square wave and random signal, the received signal is obtained through the mixture matrix of the Gauss channel, and the original signal is processed by the blind source separation algorithm based on negative entropy.
