摘要
介绍了某辗环机数字控制系统的研制，提出了采用定值反馈闭环控制方法跟踪目标值曲线。设备安全保护时间继电器参数可根椐实际工况自动设置，整个系统实际使用效果良好。
The research of a practical DDC system is presented. It's achieved to trace the target curve by feedback loop system with fixed feedback value.Value of timer relay for security is automaticaly set. Whole system is proved more usefully by practical use.
