摘　　要：研制了一种以可编程控制器为核心器件 ,通过软件方式实现 CO2 弧焊机器人电弧电压及焊接电流合理匹配的智能控制系统 .系统通过具有修正因子自寻优功能的自组织模糊控制器维持所选定的焊接电流不变 .同时 ,系统针对 CO2 焊的短路、半短路和细颗粒过渡焊的电弧电压采取不同的自寻优目标和寻优方式进行寻优 .寻优后的电弧电压与焊接电流形成合理匹配 ,达到了稳定熔滴过渡过程 ,减少飞溅 。Intelligent control system is developed,the core of which is Programmable Logic Controller, in order to keep the reasonable matching of arc voltage and welding current for CO 2 arc welding robot. With the self organizing fuzzy unit of self optimizing adjustment factor, the system can keep the current stable, which is set initially by the welding operator. Arc voltage under short circuit transition?half short circuit transition and small grain transition is optimized on the base of the different targe...
