【Abstract】 The switching off of a compressor just for a delay has been eliminated by combining fuzzy control with pulse width modulation via hardware. Fuzzy control hardwares have been designed using AC frequency conversion technology for household refrigerators. Fuzzy model of pre refrigeration is built by software for the fuzzy controller of household refrigerator for the first time and fuzzy modeling flowchart of and three bases of well performed fuzzy rules are established. The advantages include fewer rules? convenient programming?faster execution rate and strong maneuverability. Refrigerators can perform at most four pre refrigerations. And the number and duration of pre refrigerations are variable according to flowchart.更多还原
