刘金坤先进PID控制第二版第三章的仿真程序(Advanced PID control刘金坤Chapter III of the second edition of the simulation program)

说明：  matlab矢量控制系统仿真图，电机数字模块，三相转两相模块(vector control system )

说明：  在为分割使用分水岭变换之前，通常使用梯度幅度来预处理图像。(Before using watershed transformation for segmentation,we usually use gradient magnitude to preprocessing the image. )

adaptive filtering with matlab

对一张人脸图像进行LBP处理，提取LBP特征并输出(LBP on a human face image feature extraction and output)

检测电机转速通过pid算法对电机PWM占空比调节使电机达到预定转速(The motor speed is detected, and the duty cycle of the motor PWM is adjusted by the PID algorithm, so that the motor reaches the desired speed)

Here is a matlab code for describing the effect of shadowing in the wireless channel

说明：  48MW风电场Simulink仿真，共24台风机，含10Mvar无功补偿装置，可实现定电压定无功控制。(48MW wind farm Simulink simulation, a total of 24 fans, including 10Mvar reactive power compensation device, can achieve constant voltage constant reactive power control.)

低通滤波器，对数据进行平滑，也叫做最小二乘法，Savitzky-Golay算法(a particular type of low-pass filter, well-adapted for data smoothing, and termed variously Savitzky-Golay, least-squares, or DISPO (Digital Smoothing Polynomial) filters. Rather than having their properties defined in the Fourier domain and then translated to the time domain, Savitzky-Golay filters derive directly from a particular formulation of the data smoothing problem in the time domain)

一种时频变换方法—伪Margenau-Hil分布，用于信号时频分析。(Of a time-frequency transformation method- Pseudo Margenau-Hil distribution for signal time-frequency analysis.)
