The Temperature Fuzzy Control System of Barleythe Malt Drying Based on Microcontroller

The control strategy of temperature and humidity in the beer barley malt drying chamber based on fuzzy logic control was implemented. Expounded in this paper was the selection of parameters for the structure of the regulatory device, as well as the essential design from control rules based on the existing experience. A temperature fuzzy controller was thus constructed using relevant fuzzy logic, and humidity control was achieved by relay, ensured the situation of the humidity to control the temperature. The temperature’s fuzzy control and the humidity real-time control were all processed by single chip microcomputer with assembly program. The experimental results showed that the temperature control performance of this fuzzy regulatory system, especially in the ways of working stability and responding speed and so on, was better than normal used PID control. The cost of real-time system was in quite competitive position. It was demonstrated that the system have a promising prospect of extensive application.
