摘　　要：脉冲ＭＩＧ／ＭＡＧ焊接熔滴过渡的控制是焊接技术领域的一个重要研究课题。本文提出采用自适应模糊控制方法对脉冲ＭＩＧ／ＭＡＧ焊接熔滴过渡进行在线实时控制，建立了以全数字控制ＩＧＢＴ逆变弧焊电源核心的自适应模糊控制系统。基于Ｆｕｚｚｙ控制理论和大量脉冲ＭＩＧ／ＭＡＧ焊接工艺实验结果。Control of droplet transfer in pulsed MIG/MAG welding is one of the important research projects in welding technology. In this article, the authors puy forward an idea of on line real time control of droplet transfer in pulsed MIG/MAG welding based on self adaptive fuzzy control and developing a system with fully digital controlled IGBT inverter arc welding power supply as its core. On the basis of fuzzy control theory and the experimental results of pulsed MIG/MAG welding technology, the authors have designed this self adaptive fuzzy control system and made application practices.
