为系统辨识，神经网络初学者提供一种简单的程序设计方法，希望大家多多共享，互利互惠。(In order to identify the system, the beginners of the neural network provide a simple method of programming. We hope that all of us can share more, mutual benefit and mutual benefit.)

VC++ 源码编译实现的计时器小程序，比较简易的计时器，比秒要再快一些，不过这个时间频率是可以调的，如图所示，点击开始计时功能，计时器就开始工作了，可看到数字在不停的增大。(Timer applets VC++ source compiler implementation, relatively simple timer than seconds again faster, but this time frequency can be adjusted, as shown, click the start timing function the timer began working, can be see the numbers kept increasing.)

无刷双馈模型，基于matlab平台，参数可调，无保护封装(Brushless doubly-fed model, based on matlab platform, adjustable parameters, unprotected package)
