This code applies global histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The output is definitely a better contrast image as compared to the input

广义最小方差自校正控制：在求解控制律的性能指标中引入对控制量的加权项，限制控制作用中的剧烈变化。(Generalized minimum variance self-tuning control: control the amount of weighted items, solving the performance of the control law introduced to limit the dramatic changes in the control action.)

PMSM control By PWM signal

1、利用自相关法找出含有大量数据的周期信号的周期 2、利用互相关对齐含有大量数据的多路采样信号以便分析 3、使用分段平滑经过求导后的含有干扰的图像曲线(1, using the autocorrelation method contains large amounts of data to identify the period of the periodic signal 2, using the cross-correlation contains a large amount of data aligned with the sampling signal for the multiplexed analysis, the use of segmented through derivative after smoothing with interference by the image curve)
