| Abstract: | Bag dedusting control system in steelmaking workshop of a certain steel works is introduced.In the system,Simatic S7-400 PLC,and industrial Ethernet and Profibus-DP were adopted.Variable resistance control strategy was used to control bag pulse dedusting,and fuzzy control algorithm was used to control flue gas temperature in collector.Empirical formula of resistance target is given.Practical operation shows that the system is stable and reliable,and its dedusting efficiency and control accuracy are high. |
