it is about analysis of picture using matlab.

说明：  该段程序是AM调制，其中包括调制信号，载波和已调信号的时频分析(The section of program is AM modulation, including modulation, carrier and modulated signals time-frequency analysis)

采用小波分解系数阈值量化方法进行去噪处理的程序(Wavelet coefficients thresholding denoising procedures)

说明：  运用粒子群算法自动修正BLDC的PID参数，视电脑情况需要运行一段时间才能出结果，可自己修改粒子群参数(The PID parameters of BLDC are automatically modified by particle swarm optimization algorithm, and the results can only be obtained after running for a period of time depending on the situation of the computer. You can modify the parameters of particle swarm by yourself)
