摘要: 研制一种以16位80c196kc数字单片机为核心器件,通过自主开发软件实现基于降低操作技能依赖性的模糊控制系统。系统设计了2个模糊控制器。其中的PID参数自适应模糊控制器的任务是补偿电弧电压寻优控制过程中焊接电流的偏差,使由操作者焊前所设定的焊接电流保持不变。另一个模糊控制器的任务是在设定电流下对电弧电压进行以实现最高短路过渡频率为目标的自寻优。通过2个模糊控制器的控制自动使电弧电压与设定焊接电流形成最佳匹配,摆脱在规范参数选择上对操作技能的依赖性。

Abstract: In order to reduce dependence of operating skill, fuzzy control system is developed, the core of which is a 16 bit single chip microcomputer of Intel 80c196kc. It is realized by software programming. In this system two fuzzy controller are designed. The PID parameter selfadjusting fuzzy controller is used to compensate welding current deviation in the process of are voltage optimized control. To obtain the optimum result of ultimate frequency of short circuit transfer, the self-optimizing fuzzy controller carries out the are voltage self-optimizing by under the condition of the given welding current. Are voltage and welding current are kept the optimum matching relationship by two fuzzy controllers.
