The characteristic of components in blast furnace pulverized coal injection (PCI) control system and PCI rate adjustment methods were analyzed. PCI control system is a dynamic, time-varying, with strong disturbance, nonlinear, MIMO plant. The technologies of PCI rate measurement and control were investigated and analyzed, and the problems of PCI control system such as measurement precision and control adaptability were pointed out. A prospect which intelligence control serves as a new solution to the problems,was also represented.
