基于Step7和WinCC的焦炉集气管压力分级控制系统

Coke Oven Gas Collector Pressure Hierarchical Control System Based on Step7 and WinCC

摘要:

针对采用常规控制方法对焦炉集气管压力控制效果差、无法满足要求的现状,运用模糊控制和解耦控制原理以及Step7和WinCC软件,在已有焦炉集气管压力控制系统基础上提出一种基于模糊解耦控制的分级控制系统；介绍系统控制策略、程序开发、监控界面设计及系统运行调试等；运行表明:该系统控制效果良好,其控制精度、抗干扰能力等技术指标优于原指标。

Abstract:

Status conventional control methods for coke oven collector pressure control is poor, unable to meet the requirements, the use of fuzzy control and decoupling control theory and software WinCC Step7 and proposes a coke oven collector pressure in the existing control system based on hierarchical control system and fuzzy decoupling control. Describes the system control strategy, program development, monitoring, interface design and system operation and commissioning. Run showed that:the system control works well, the control precision, anti-interference ability and other technical indicators better than the original target. 
