数控轨迹焊接模糊控制焊缝跟踪技术

The Technology of Welding Trace Using Uncertain Control

论述了在自行研制的四座标数控轨迹焊接机器中，根据工作时焊接电流的变化，运用模糊控制理论，实现焊缝轨迹的准确跟踪这一关键技术。

The article deals with the four-axis NC welding machine. Based on the welding current change, using uncertain control, the correct welding trace can be realized.
