Here is a lumped parameter model of a hydraulic transmission line. The line is modeled by one, two, three, four and ten lump models. The simulation program presents the transient response in addition to experimental results.

数字PID的matlab仿真程序，针对刘金琨的先进PID控制的matlab仿真，里面的部分程序进行了修改 第六章(Digital PID of matlab simulation program for Liu Jinkun matlab advanced PID control simulation, which part of the program were modified Chapter)

该程序是在flac下运行的，没找到flac，所以用matlab表示了，供岩土力学研究方向学习(The program is run under flac, did not find flac, so use matlab shows for rock mechanics research study)

对输入的语音信号运用短时能量函数进行去静音，然后把去掉静音帧之后的信号进行重组。(remove the mute of the speech signal (using short-term energy function), and then remove the signal mute frame after restructuring.)

数据的最小二乘法拟合，曲线绘制，实用的MATLAB数据分析使用，适合大数据分析(Least squares fitting of data and curve drawing)

说明：  求解语音信号的短时过零率、短时能量、短时自相关特征，分析实验结果，并能掌握借助时域分析方法所求得的参数分析语音信号的基音周期及共振峰。(The short-time zero-crossing rate, short-time energy and short-time autocorrelation characteristics of speech signal are solved, and the experimental results are analyzed. The pitch period and resonance peak of speech signal can be analyzed by the parameters obtained by time-domain analysis method.)
