【Abstract】 In this paper,a new type of temperature control system for plastics extrusion,the fuzzy controller,is analyzed and researched.AT89C52 was used as mainly controlled chip and AD595 was used to magnify signal which collected from thermocouple with reference junction compensation.At the same time,AD650 and CD4051 was used for V/F transition and signal analysis.A fuzzy control tablet was acquired by summarizing temperature fuzzy control rules,and software was developed in according to the fuzzy control tablet.The system was characterized as little volume,low cost,powerful and intelligent.更多还原
