An Application of Fuzzy Control Based on PLC in the Pressure Control System of Chinese Medicine Water Extraction
The water extraction system of Chinese medicine exists problems for the control object characterized by multi-variables, large delay, nonlinearity and difficulty of building model. The method which applies intelligent fuzzy control on Chinese medicine extraction process is proposed. The key factors which influence the pressure in extraction tank are concluded in the basis of analysing water extraction process of Chinese medicine. The design of fuzzy controller is also completed. According to the characteristics of PLC, the fuzzy control is successfully used in PLC. From the simulation results, the fuzzy control is superior to that of the traditional PID control. The fuzzy controller has a good rapidity, stability and stronger robustness.
