Abstract

Método y medios para controlar una celda electrolítica para la produccion de aluminio mediante insumos para control del procedimiento, que comprende medios para la medicion de una o más de variable/s de procedimiento, en donde el/los valor/es medido/s son conducidos a un estimador. El estimador puede ser del tipo del filtro de Kalman, y estima el valor actual de una o más variable/s de procedimiento seguido del pronostico del valor de dichas variable/s de procedimiento y/u otras variable/s de procedimiento. El/los valor/es pronosticados es/son usados para calcular futuros bosquejos de acciones hipotéticas para control de insumo por medio de un calculador, El pronostico de las variable/s de procedimiento se efectua conforme a un modelo dinámico no lineal que es parte integral de un control de procedimiento.Method and means for controlling an electrolytic cell for the production of aluminum by means of inputs for process control, comprising means for measuring one or more of the process variable (s), where the value / s are measured / s are conducted To an estimator. The estimator can be of the Kalman filter type, and estimates the current value of one or more procedure variable / s followed by the forecast of the value of said procedure variable / s and / or other procedure variable / s. The predicted value (s) is / are used to calculate future sketches of hypothetical actions for input control by means of a calculator. The forecast of the procedure variable / s is made according to a non-linear dynamic model that is an integral part. of a procedural control.
