说明：  the linear ARX model as shown below [12] is used to represent the input and the output data for the system. This ARX model is utilized for both Least Square (LS) and Recursive Least Square (RLS) algorithms. It is one of the simplest statistical methods for system identification used to find the transfer function for the model. The equations given by [15]: Y=φβ+ξ (7) β=〖(φ^T φ)〗^(-1) φ^T Y (8) where Y is the predicted output. φ is includes actual input and output parameters. β is includes parameters to be estimated.

说明：  一个用MATLAB实现的CA滤波模型，适合初学者，文件不长稍微有点基础的都能看懂(A the CA filter model using MATLAB, for beginners, file does a little bit of foundation can understand)

基于MATLAB平台的PWM调制正弦波的快速傅里叶分析(his model simulates and computes Fourier analysis of PWM based sinusoidal waveform. Fundamental frequency can be changed in model properties. Amplitude modulation index and frequency modulation index can be adjusted in Simulink model directly.)

利用FOCUSS算法对数据进行重构表示，得到需要表示的成分，减少噪声干扰。(FOCUSS algorithms use the data to reconstruct said component required to obtain representation, reducing noise.)

说明：  输出电压稳定不随输入电压、输出侧负载变化而变化，电流电压环pi参数已整定完毕，内外环配合良好。(The output voltage stability does not change with the input voltage and the load at the output side. The PI parameters of the current voltage loop have been set.)

说明：  MATLAB实用程序百例,三角函数曲线/三维曲线图等，包括了MATLAB数据分析作图的主要内容(100 cases of MATLAB utility, trigonometric curves/three-dimensional curves, including a MATLAB data analysis mapping the main content)
