用MATLAT编的FFT程序，在MATLAB环境下可以显示波形。()

应用最小二乘法对二阶系统进行辨识，得到相关参数(Application of least squares, second order system identification, are relevant parameters)

汽车线性二自由度模型，研究汽车转向的有用(Automotive Linear two degrees of freedom model of research useful for automotive steering)

这是Hammerstein系统加输入死区的递推增广最小二乘法参数辨识程序，可以运行。(This is a plus input recursion system Hammerstein dead Augmented least squares method parameter identification program can be run.)

说明：  小波分析从基础到高级应用的matlab源码例程~~(Wavelet analysis of matlab source routines ~ ~)

Simple function to adjust filter coefficients using the LMS algorithm adjusts filter coefficients, b, to provide the best match between the input, x(n), and a desired waveform, d(n),both waveforms must be the same length, uses a standard FIR filter

利用EM算法对状态空间模型中的参数进行辨识，效果良好(The EM algorithm is used to identify the parameters in the state space model, and the result is good.)
