| 摘 要： | 在DSP控制逆变电源的基础上,介绍了以CO2焊接过程中熔滴过渡频率的模糊控制系统的设计方案,设计出了以熔滴过渡频率的偏差以及偏差的变化率为输入量,而以熔滴过渡中开关管IGBT的占空比的变化率为输出量的模糊控制器.配合原有的主电路,加上研制的控制系统,对其外特性进行了测试,测试表明控制系统能自动调整波形,保持焊接频率的稳定,实现了电源的恒流外特性控制.

| Abstract: | On the basis of DSP-controlled inverter,the design project of the fuzzy control system of droplet transfer frequency in CO2 welding is introduced.The fuzzy controller was designed , it regards the error of droplet transfer frequency and the error changing rate as two inputs,single output is the changing rate of IGBT duty circle.In the foundation of main circuit developed, the fuzzy control system was tested.The result indicated that the system can adjust the waveform automatically,and stabilize the frequency of the arc welding,and realize the control of constant current outside characteristic. |
