This paper presents an intelligent control method of hot metal co-inject desulfuration which includes the expert setup model of desulfuration (ESMD) and the generalized feedback control mechanism (GFCM). ESMD is applied to the confirmation of the setup for the injection control system according to the experience data, and GFCM is applied to the reduction of the setup errors due to the changes of boundary conditions. The method has been implemented in the desulfuration control system design of certain steel plants and the results have satisfied the production demand.
Keywords: intelligent control, process control, expert system, optimization, qualitative analysis
