A Matlab script to simulate a Phase-Locked Loop (PLL). This is a type II PLL ie it has two integrators (one of these is the VCO itself). It is simulated with an FM (frequency modulation) input. The output is the demodulated baseband signal

QPSK发送机，信号源为随机二进制序列，经串并变换后，转换成双极性信号发送(QPSK transmitter, the signal source for random binary sequence, series and transform, change the polarity signal sent in pairs)

对于非线性时变工业过程对象，首先建立模型集来覆盖被控对象动态特性，分别建立相应的内模控制器，在系统变工况运行时，进行多模型加权自适应控制，与传统单内模控制相比，控制效果明显提高。(For the nonlinear and time-varying industrial process object, first ，we build model set to cover the dynamic characteristics of the object, then,set up a corresponding internal model controller respectively.When the system operation mode is running, multiple model weighted adaptive control has been used,and compared with the traditional single internal model control,it has improved obviously. )

说明：  本篇文章介绍了基于Matlab环境下的地面模型构建，采用了合适的插值拟合函数实现了构建。(This article describes an environment based on Matlab model of the ground, using a suitable fitting function interpolation building.)

UKF和KF的实现。并通过输出图像比较两者的区别(UKF and the KF implementation. By comparing the difference between the output image)

保证准确无误，是学习通信的好帮手，基于SVPWM的三电平逆变的matlab仿真，部分实现了追踪测速迭代松弛算法。( Ensure accurate communication is learning a good helper, Based on SVPWM three-level inverter matlab simulation, Partially achieved tracking speed iterative relaxation algorithm.)

用递推最小二乘法进行系统辨识，包括simulink环境下搭建模型以及源代码(recursive least square （RLS）source code)

利用matlab的gui设计的带有输入和输出功能的界面图形，实现等距线可视性很强，自己独立编写的数据和图形，学习非常值得,实现 ga pca bp和svm压缩图像，matlab语言(Using GUI of MATLAB to design interface graphics with input and output functions, realizing the visibility of isometric line is very strong, and it is very worthwhile to study the data and graphics independently written by oneself, realizing GA PCA BP and SVM compressed image, MATLAB language)
