介绍了一种利用 80C196KC数字单片机通过所编制软件方式实现的模糊控制系统。系统可以在焊接过程中消除网路电压波动对CO2 短路过渡焊电弧电压的影响 ,达到稳定短路过渡频率的目的。
This paper introduces a kind of fuzzy control system which is realized by 80C196KC digital single chip computer through the software. The system can eliminate the influence of network voltage fluctuation on the arc voltage of CO2 short-circuit transition welding during welding, and achieve the purpose of stabilizing the short-circuit transition frequency.
