Abstract:On the basis of analysis on processing technology of tea, the fuzzy algorithm was applied to realize the intelligent control of traditional tea cylinder waterremoving machine. By detecting the weight and grade of fresh tea leaves in the tea cylinder waterremoving machine, the fuzzy control rule of decisionmaking was used to adjust time and temperature of tea waterremoving realtimely; at the same time, fuzzy proportionintegrationdifferentiation (PID) controller was used to adjust temperature of tea waterremoving to realize the accurate control. Data acquisition and double fuzzy control system hardware were made up with NI USB-6215 data acquisition card and Siemens programmable logic controller (PLC), etc. In addition, output effect of double fuzzy control system model was tested by laboratory virtual instrument engineering workbench (LabVIEW). Finally, the possibility of the double fuzzy control system was proved by the substantial evidence and the result of tea waterremoving was tested. Experiment result show that this control system output parameters are ideal for the waterremoving of tea, the temperature departure of waterremoving is less than 1℃ and the time deviation of waterremoving of tea is less than 5s. This control system can reduce the human factors in the process of teamaking. Whats more, it will improve the intelligent level of the machine for teamaking.
