Automatic temperature control system of zanthoxylum drying room based on fuzzy-PID

At present, the temperature of the zanthoxylum drying room is controlled manually in China. It has some disadvantages such as non-uniform drying, slow drying rate and high energy consumption. Therefore, in order to improve the drying quality, an advanced automatic temperature control system based on fuzzy-PID was proposed to apply in drying zanthoxylum. The functional characteristics of PID technology, fuzzy control technology, and fuzzy PID control technology were compared in the paper, and the 32-bit ARM processor was combined with the GPRS technology to realize the automatic control and the remote alarm in the zanthoxylum drying room. The inconvenient communication problem of automatic control equipment was solved. The automatic temperature control system based on fuzzy-PID could provide an effective solution scheme for automatic zanthoxylum drying in the rural area of China.
