摘要
等速送丝系统中电弧的控制是一个极为重要的环节,其控制质量的好坏直接影响到焊接过程的稳定。本文研究了一种模糊神经网络控制器,该控制器根据给定电压与反馈电压的误差和误差变化率,能够自动调整隶属函数和控制规则,具有自学习和自适应能力。
In the constant speed wire feeding system,it is very important to control the arc. And this can directly have effect on the stability of welding process.This paper studies a fuzzy neural network controller.It can adjust the membership function and control rules according to the error between given voltage and feedback voltage and the error＇s change rate.
