摘要
针对传统控制中存在的自动化程度低的问题,开发研制了基于PLC的PID控制算法的物料定量给料系统计量装置,阐述了该控制系统的结构及PLC的硬件组成;根据工艺过程的技术要求,从控制系统的硬件配置到应用程序的设计,系统地考虑了工业物料定量给料过程的实际情况。应用结果表明该系统性能稳定、运行可靠、人机界面直观灵活,控制系统实现的各项功能均满足工艺要求,取得了良好的应用效果。
Aiming at the existed in control of the low automatic degree is developed, based on PLC PID control algorithm is material feeding system, quantitative measurement device, expounds the structure of control system and PLC hardware composition, According to the technical requirement of process control system, from the hardware configuration to the application of the system, the design of industrial materials to consider ration the actual situation of process. Application shows that the system is stable and reliable operation, man-machine interface intuitive, "flexible control system to realize the functions meet the technological requirements, and achieved good application effect.
