Abstract
According to the non-linearity and large-lag phenomena in temperature and humidity in hot air drying process, conventional PID control and fuzzy control were combined using fuzzy PID control theory in the system. A Fuzzy PID controller was designed to achieve the PID parameters’ online self-tuning. Results: when the target temperature is set at 15 ℃, compared with the conventional PID control, the maximum overshoot of the hot air drying control system based on fuzzy PID control is decreased by 3 ℃, the adjustment time is reduced by 10 min and the steady state error is ± 0.5 ℃, with better dynamic and static response characteristics, and in the case of parameter changes can better adapt to the hot air drying oven engineering applications.
