To obtain optimum operation of an alumina reduction cell, it is important to keep the alumina concentration in the cell within a certain range. This will reduce anode effect frequency and stabilize the cell operation. However, it is not possible to measure this concentration directly. In the system presented here, the characteristic nonlinear relation between the alumina concentration and the cell resistance is modelled by an adaptive linear model where the estimated parameters give information about the concentration. This information is then used to control the alumina supply to the cell. In addition, the system controls the energy input to the cell by keeping the average resistance close to a reference value. |
