Design of Fuzzy Controller for Flue Gas Temperature of Dedust With Self-set Correction Factor
Complex and diverse Parameters, wide fluctuation of work condition which control of flue gas temperature system for dedust is faced with. According to present status above this paper put forth a fuzzy controller with Self-set Correction Factor, and it dimly deduces turndown ratio of mixer valve according to temperature values of multipoints and their variations.The application examples show that: In the bagfilter dedust system for 30 ton electric furnace in nantong baosteel iron & steel co., ltd, mixing airflow when adopting flue gas temperature fuzzy control with self-set correction factor is more reasonable than that when adopting ordinary simple fuzzy control and fuzzy control with set correction factor. It is obtained by speed-frequency variable. Not only prevents burning bags at high temperature and dewing at low temperature, but also lets mixing airflow adjust to the optimum value.It can reduce 30％ of mixing airflow,irnprove l0-20％ of total flue gas collecting efficiency.
