摘　　要：针对纯模拟器件自耗电极真空电弧炉电极升降控制系统故障率高、维护量大等一系列问题,设计出了由PLC和模糊控制组成的电极升降控制系统。介绍了系统主要硬件配置,并给出了主程序循环块方框图。该系统控制算法采用模糊控制算法,且根据现场工艺要求实现了从手动到自动的无扰切换功能。实验运行数据表明,基于模糊控制规律的电弧炉电极升降PLC控制系统运行稳定可靠,操作方便,维护量小,对同行业的生产将起到推动作用。Aiming at a series of problems such as high failure rate ,a great deal of maintenance resulting from the self-consumption electric pole vacuum arc furnace electric pole fluctuation control system consisting of simple analog device, the electric pole fluctuation control system consisting of PLC and fuzzy control is designed. The main hardware of the system and the skeleton diagram of the main program circulation block is also given. Fuzzy algorithm is adopted in the system, and the function of non-disturbance shifting from manual mode to automatic mode is realized according to field process requirement. The date got from field manifests that arc furnace electric pole fluctuation PLC control system based on fuzzy control rule has features of stable running, convenient operation and little maintenance. The system will promote and impulse function to production advancement of the same trade.
