摘　　要：介绍了带有模糊控制器的脉冲电源设计，其脉冲电流幅值Ｉｐ和宽度ｔｐ，或Ｉｐ、ｔｐ的脉冲基值电流幅值Ｉｂ和宽度ｔｂ均可随光纤光电传感器检测的焊缝焊透质量进行自适应调节，且脉冲频率ｆ将被优化控制在某个期望值附近。A design of pulsed power source for arc welding with fuzzy controller has been suggested in this paper.The pulsed current amplitude I pand duration t por I p, t pbased current amplitude I band it′s duration t b can be adjusted adaptively according to real time penetration quality detected using optic fiber photocell sensor during arc welding process,so that the pulse frequency f will be controlled near expected value.
