Data-Driven Robust RVFLNs Modeling of a Blast Furnace Iron
· Abstract Optimal operation of a practical blast furnace (BF) iron-making process depends largely on a good measurement of molten iron quality (MIQ) indices. However measuring the MIQ online is not feasible using the available techniques. In this paper a novel data-driven robust modeling is proposed for an online estimation of MIQ using improved random vector functional-link networks
