pld的实践教程，完整详细的讲解适用于初学者以及研究开发人员(pld hands-on tutorials, full and detailed explanation for beginners as well as research and development staff)

说明：  六相电压源逆变器PWM技术，在simulink中搭建了六相电压源逆变器PWM控制器(PWM technology of six phase voltage source inverter)

说明：  tcpcrypt是一种协议，它尝试加密（几乎）所有网络流量。与其他安全机制不同的是，tcpcrypt是开箱即用的：它不需要配置，不需要更改应用程序，而且即使远程端不支持tcpcrypt，您的网络连接也将继续工作，在这种情况下，连接将优雅地返回到标准的明文tcp。(Tcpcrypt is a protocol that attempts to encrypt (almost) all of your network traffic. Unlike other security mechanisms, Tcpcrypt works out of the box: it requires no configuration, no changes to applications, and your network connections will continue to work even if the remote end does not support Tcpcrypt, in which case connections will gracefully fall back to standard clear-text TCP.)

VMD算法，带注释解析，方便查看和理解，可直接使用(VMD algorithm, annotated parsing)

说明：  各种电机驱动的原理图 PCB 芯片手册 花了很长时间搞到的(Schematic diagram of various motor drive PCB chip manual)
