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 self adjusting
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.
