基于PLC的模糊PID控制器在热风干燥箱上的应用
Fuzzy PID controller based on PLC and application on hot air drying chamber
摘要
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 the-ory 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 1 5 ℃,compared with the conventional PID con-trol,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 engi-neering applications.关键词
