| 摘 要： | 采用直接模型参考自适应控制算法对弧长和决定熔滴尺寸的焊接电流进行解耦控制,通过调节焊接电源输出电压和送丝速度,使焊接过程中电流和弧长保持在设定值上,使得每个脉冲周期熔化的焊丝体积相等,保证每个周期中熔滴尺寸在脉冲产生之前均匀一致.仿真结果显示该算法可以实现控制对象的输出跟随参考模型的输出.

| Abstract: | A direct model reference adaptive control algorithm was applied to decouple the arc length and the welding current,which were controlled by open circuit voltage and wire feed speed to trace the output of the reference model.The results of simulation show the validity of the control method. |
