【摘要】 根据ＣＯ２ 焊试验结果，利用模糊集合理论及建立在该理论基础上的模糊控制技术，详细介绍了ＣＯ２ 焊焊缝自动跟踪系统模糊控制器的设计、模糊变量的选择及模糊量的模糊化和模糊判决的过程。利用实际的调整量Ｄ 与电流差值ΔＩｆ的关系，即可实现ＣＯ２ 焊焊缝的自动跟踪控制。更多还原

【Abstract】 According to the results of CO 2 welding experiments,the design of the weld tracking system based on the fuzzy sets and fuzzy control principle,the selecting of fuzzy variables and their fuzzification and defuzzification are introduced.Using the relationship between the welding current difference ΔI f and the real adjustment distance D,the automatic control action of weld tracking system for CO 2welding process can be realized.更多还原
