Algorithms for indirect estimation of unmeasured parameters of aluminum electrolysis process
Abstract
Due to the insufficiency of operational technological control of the process of electrolytic aluminum production, its automated control has to be based on methods of indirect estimation of unmeasured parameters. An algorithm for estimating one of the most important non-measurable parameters - the current alumina concentration in the melt - from the measured electrical parameters with their nonlinear relationship has been developed.
