【Abstract】 The fuzzy controller is applied to the inverter welding power source. The system is introduced briefly, including run principle, form of control system and hardware design. Then the two input and single output fuzzy controller is designed, and the fuzzy control table is got, that can be applied to control constant current. An inverter welding power source has been produced based on this theory, and the inverter has the excellent dynamic capabilities similarly.更多还原
