用两种递推最小二乘辨识的方法辨识吹风机函数。在加白噪声和有色噪声的情况下观察变化。两个辨识的结果与实际输出很接近，但是都会比实际的要大一点。有可能是对有色噪声的估计所引起的。噪声的增加不明显。(Identification by two recursive least squares method to identify a hair dryer functions. Observe the changes in the plus white noise and colored noise situations. Two identification results with actual output is very close, but it will be bigger than the actual. There may be an estimate of colored noise caused. Noise increase is not obvious.)

用matlab仿真轴承故障信号构造轴承故障的仿真信号，其中轴承的固有频率fn=3000Hz , 位移常数y0=5, 阻尼系数ξ＝0.1, 冲击故障发生的周期为0.01s，采样频率fs=20KHz, 采样点数N=4096。要求：根据上述条件构造轴承故障的仿真信号，画出其时域波形及频谱图。(Matlab simulation bearing fault signal)

说明：  永磁同步电机三环矢量控制，有速度环等，经测试正确(Permanent magnet synchronous motor vector control of three-ring, ring, such as speed, were the correct)

说明：  用subplot分别在不同的坐标系下作出下列四条曲线，为每幅图形加上标题(subplot were used in different coordinate system to the following four curves for each piece of the title with graphics)

说明：  lms algorethem update

this is the source code for Matlab & simulink for digital communication. this folder contains all the matlab code in the textbook.

某国外知名大学的数字信号处理算法教材，使用m语言进行编程。(AlgorithmCollectionsforDigitalSignalProcessing，E.S. Gopi National Institute of Technology, Tiruchi, India)

this source code is very good

自相关法谱估计的程序，这是一种经典的方法，效果真心不错(Autocorrelation spectrum estimation procedure, which is a classic method, the effect is really good)

说明：  matlab实现最简单的DMC 预测控制 单入单出(The simplest DMC algorithm single in single out)
