convolution

基于EMD的信号分解，在matlab中实现，信号分解，谱变换(EMD-based signal decomposition is implemented in matlab, signal decomposition, spectral transformation)

有AI比较控制的一个小程序， 用MATLAB的rule实现的AI比较。(AI car function. use MatLab to get the AI rules)

H-infinity Control Example, robust control

说明：  这是一个完善的KNN算法。算法清晰，备注明确，分类效果良好。(This is a perfect KNN algorithm. Algorithm is clear, clear notes, a good classification results.)

改进的空间平滑music方法，用于阵列信号处理的高分辨率估计(promoted music algorithm)

Matlab有关于garch的源代码，内含几个M文件，包括估计、滤波、预报等。(It is the source code of garch by Matlab, which contains several M files, including estimation, filtering, prediction, etc.)

短路仿真，可仿真接地故障、相间短路、相间短路接地。(Short circuit simulation, three-phase transformer three-phase short-circuit, single-phase short circuit, two-phase short-circuit and two-phase short-circuit ground)

examples contain source codes about PID control

说明：  通带截止频率 =1000Hz，阻带截止频率 =1200Hz，采样频率fs=5000Hz，通带衰减系数 =0.3dB，阻带衰减系数 =40dB。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter. )
