数字PD-PID控制的打号机随动系统

Digital(PD-PID) Controlled Stamper Follow-up System

介绍了碳素行业电极打号机电气传动装置随动系统的组成，分析了采用数字双模（PD-PID）控制器的工作原理并给出了程序框图．通过1a多的运行实践证明，本系统具有稳态精度高、定位准确、无振荡、快速性好等静、动态优良控制性能．

The electrode stamper have been applied in the carbon calling. This paper introduces the makeup of stamper＇s electric drive follow-up system, the controller adopts digital double model（PD-PID） method. The working principle and program frame are introduced. After one year experience, the system has high precision in stability, orientation to a crumb, no oscillation, response in time and so on. The system＇s dynamic performance is quite well.
