智能控制第二版刘金琨著。 本书较全面地叙述了智能控制的基本理论、方法和应用。此代码为次数的附带程序。(Intelligent Control Second Edition was written by Liu Jin_Kun. This book describes more fully the intelligent control of the basic theory, methods and applications. This code is the number of accompanying program.)

说明：  首先，建立两个模拟信号的数学模型 有用信号 干扰信号。两个信号的中心频率、信号带宽等参数由学生自己选定，要求两个信号的频谱不重叠 分别画出三个模拟信号的时域波形和频谱图；然后，根据x_a (t)的中心频率和带宽，按照奈奎斯特采样定理选择采样频率fs，分别对信号s_a1 (t)、s_a2 (t)、x_a (t)进行时域采样，得到离散信号s_1 (n)、s_2 (n)、x(n)。利用FFT算法分析离散信号的频谱，分别画出三个离散信号的时域波形和频谱图； 接着，设计数字滤波器H(z)，要求该滤波器对干扰信号s_2 (n)的衰减大于40dB。提出滤波器的设计指标，并设计滤波器，给出滤波器的设计结果，绘制滤波器的幅频特性和相频特性曲线，验证滤波器的设计结果是否达到设计指标要求；此外，选择实现数字滤波器H(z)的结构，画出滤波器结构信号流图；然后，将合成信号x(n)输入数字滤波器H(z)，按照所选择的滤波器结构，设计计算机程序计算滤波器的输出响应y(n)，画出y(n)的时域波形和频谱图；(the synthetic signal x (n) is input into the digital filter H (z). According to the selected filter structure, a computer program is designed to calculate the output response y (n) of the filter, and the time-domain waveform and spectrum diagram of Y (n) are drawn)

自己做的一个针对mdb中数据集构建拓扑，并进行拓扑验证的例子，之前找半天没有找到相关的，自己做的这个还是可以用的，希望能帮到有需要的人士(Examples of their own to do a build topology for mdb data sets and topology verification, before looking for a long time did not find the relevant own doing this can still be used, I hope to help those in need)

无损卡尔曼滤波源程序，可读性强，适用范围广，可在此基础上做进一步改进(Kalman filter lossless source, readable, wide application, can be done on the basis of further improvements)

基于SVPWM的三电平逆变的matlab仿真，利用matlab GUI实现的串口编程例子，有借鉴意义哦，代码里有很完整的注释和解释，对于初学者具有参考意义，FMCW调频连续波雷达的测距测角，matlab小波分析程序。(Based on SVPWM three-level inverter matlab simulation, Use serial programming examples matlab GUI implementation, There are reference Oh, Code, there are very complete notes and explanations For beginners with a reference value, FMCW frequency modulated continuous wave radar range and angular measurements, matlab wavelet analysis program.)

The Schumann resonance frequencies are a set of eigenmodes in the extremely low frequency (ELF) portion of the electromagnetic field spectrum. These frequencies are only present for planetary-like bodies with a substantial ionosphere acting as a perfect electric conductor, thus forming a resonance cavity with the surface. In this example, the Schumann resonance frequencies for the Earth are calculated.
