摘要
利用软件取代模拟和数字器件的数字化控制,提高了产品的集成度,增强了系统的柔性和智能性。本文介绍了一种基于TMS320F240的UPS数字化控制技术,提出了一套融合软硬件的数字化系统软件控制方案,实现了UPS的各个功能模块。文中首先设计了软件锁相环;然后实现了输出电压瞬时值和有效值双闭环反馈控制。通过实验证明了该系统的可行性和先进性。
Digital control, in which software replaces analog and digital instruments, can increase the integration of the product, promote the flexibility and intelligence of the system.This article introduces a kind of digital control technology based on TMS320F240 and put forward a digitalized software control project.The system software can realize each functional module in the UPS.Firstly, the software phase-closed loops is designed ;secondly, the double closed loops control of the instantaneous value and the virtual value is realized.Experiments have verified the system＇s feasibility and advantage.
