In order to reduce dependence of operating skill fuzxy 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 fvzxy controller are designed. The PID parameter self-adjusting.fuzxy controller is used to compensate welding current deviation in the process of arc voltage optimized control. To obtain the optimum result of ultimate frequency of short circuit transfer, the self-optimlzing fuzzy controller carries out the arc voltage self-optimizing by under the condition of the given welding current. Arc voltage and welding current are kept the optimum matching relationship by two fuzzy controllers. 相似文献
