Tous les fabricants de variateurs de vitesse, qu’ils soient industriels ou bien distributeurs de matériel à usage pédagogique proposent des variateurs pour machine asynchrone. Historiquement, sont apparus sur le marché des variateurs dits à « U/f = constante » et plus récemment les variateurs à contrô le vectoriel de flux avec ou sans capteur.

说明：  一个MATLAB的应用程序，很方便的！使用时需要转换为M文件。(a MATLAB applications, a convenient! Use need to change for the M documents.)

这是一个关于遗传算法解觉非线性函数优化问题的函数，通过它，你可以自己设计初始化参数来求解问题(It is used for some very different problems such as some unliner function)

用于多重回归分析的自编函数,能够画出回归曲线，列出表格。(Multiple regression analysis for self function, to draw the regression curve, listing form.)

pwm rectifier which work in open loop for traction systems.matlab simulink modal is aasigned with it.

用VC6.0编写的对话框程序，可以读取ECG（txt格式）数据，并画图。采用差分阈值法对心电信号进行R波的检测并显示R波检测的个数，效果较好。程序中也编写了一个滤波器对心电数据进行滤波。(VC6.0 prepared by the dialog box procedure, you can read ECG (txt format) data, and drawing. Differential threshold method ECG R-wave detect and display the number of R-wave detection, the better. The program also write a filter for filtering the ECG data.)

在matlab中，通过space carving实现三维重构(n the matlab, through space carving realize 3 d reconstruction)

说明：  螺旋桨PID控制 In response to constant pressure to design more efficient, faster, smaller, and better systems, engineers are constantly looking for ways to improve existing designs or replace them with better ones. Facing large fuel costs, the aerospace industry in particular has been researching alternative designs to increase fuel efficiency and performance. One such alternative is the development of reconfigurable aircraft wings. These wings would be able to adapt to the current environment increasing lift or reducing drag when appropriate.
