钢琴演奏评价系统研究 关键词：音乐识别特征提取 STFT 调式自动判别匹 配比较(Piano Performance Evaluation System Keywords: music recognition feature extraction STFT mode automatically identify matching comparison)

说明：  积分分离PID算法的思想是：当被控量与设计的偏差量偏差较大时，取消积分量，以免积分量使系统稳定性降低，超调量增大；当被控值接近定值时，引入积分控制，以消除静差，提高系统精度。(integral separation PID algorithm thinking is this : When the volume charged with the design of larger deviations deviation, the abolition of Integral volume, the volume so integral to reduce the system stability, over-regulation increased; When charged with setting value approach, the introduction of integral control to eliminate static error and improve system accuracy.)

自学matlab实用。自学Matlab必备的60个小程序代码(Matlab practical self-study. 60 small self-Matlab essential program code)

遗传算法程序，运行环境为MATLAB，可移植性非常好。程序本身不存在错误。(Genetic algorithms program, run the environment for MATLAB, portability is very good. Process itself does not exist error.)

主成分分析和独立成分分析，可以进行信号处理(Principal component analysis and independent component analysis, signal processing)

实现图像中值滤波、均值滤波等图像处理功能(Median filtering of image processing functions such as image)

说明：  《ofdm关键技术与应用》（汪裕民）一书中第10章有详细说明，在MATLAB上跑过，没有问题(&quot Ofdm technology and application&quot (Wang Yumin) Chapter 10 of the book are detailed in MATLAB, Running, no problem)

说明：  Z-transform in digital signal processing

Nothing to do, we need to learn how to trick something on the webs

说明：  另外一个模糊pid控制器matlab程序，没有用到simulink，但也很实用，希望对大家有所帮助！(good)
