在matlab中，绘制图像的灰度直方图，并均衡化复原图像(In matlab, rendering the image histogram, and equalization restored image)

glcm on dwt to get features

本模型是基于matlab Simulink搭建的PQ控制和下垂控制模型，可以用于微电网的并网和孤岛运行PID参数已经调好，效果理想，可以供参考。(This model is based on the model of PQ control and droop control built by MATLAB Simulink. It can be used in the parallel operation of microgrid and islanding operation. The PID parameters have been adjusted, and the effect is ideal, which can be used for reference.)
