A method and device for identification or precalculation of process parameters of an industrial time-variant process

摘要

This invention concerns a process for identification of pre-calculation of parameters of an industrial process, particularly in a basic industry plant with particularly quickly changing process parameters or disturbances which affect the process. The process parameters to be identified are determined by means of a process model as a function of measured values from the process. The process model comprises at least one time-invariant or substantially time-invariant process model, which represents an average-time model of the process, and at least one time-variant process model, which is coordinated with at least one time constant of a disturbance or a variation of parameters of the process.
