摘要
针对电石炉的三相电极电流耦合和PLC的控制特点,提出了一种基于PLC的模糊控制方法,将多变量模糊控制器分解成3个多输入-单输出的模糊控制器。系统硬件由PLC及其输入/输出模块组成,其控制功能由PLC程序实现,并成功应用电石炉控制系统中,实现了电极调节的模糊解耦控制。现场运行数据表明,该控制系统可靠性高,控制效果良好。
In view of CaC2 furnace system with coupled three-phase current and the control feature of PLC, a fuzzy-control method based on programmable logic controller（PLC） is proposed. The fuzzy multi-variant controller, composed of PLC and its ordinary I/O modules, is separated into three multi-input and one-output controller. The control function is implemented by PLC software. The controller is applied to CaC2 furnace control system to realize electrode decoupling fuzzy control. The results indicate that the control system is of high reliability with hizh efficiency.
