Multi-model integrated intelligent control expert system for blast furnace ironmaking

A multi-model integrated expert system was proposed to achieve the optimum control for blast furnace ironmaking process.The expert system is an integration of automatic control models,e.g.mechanism model,automatic fault diagnosis model,system optimization model,hybrid dynamic mechanism and intelligent control equation.On basis of ensuring the smooth operation of the ironmaking process,the expert system optimizes several critical model parameters.The nonlinearity of energy consumption was revealed from analysis of the hybrid dynamic mechanism of the ironmaking process,and the optimal state of process variables for different productive objective was obtained.The practical conditions were accurately predicted and different control measures were also proposed.Thus the technological goals of saving energy and increasing output were achieved.
