| Abstract: | A PID Fuzzy adjustment method is introduced in this paper, which controls the dehydrating process of fruits and vegetables. In the process, a device with heat from the condenser of a refrigerator and inner air circulation was used. The experimental results by PID and PID Fuzzy control were compared, which indicates that PID Fuzzy is better in reducing temperature oscillation, shortening transition time and keeping temperature constant and gives a satisfied control. |
