Method and device for identifying or precalculating process parameters of an industrial time-variant process

摘要

Method for identifying or predicting process parameters of an industrial process with variable process parameters or disturbance variables affecting the process, wherein the process parameters to be identified are determined by means of a process model as a function of measured values from the process, and wherein the process model is at least one time-invariant or one time-invariant Process model (1, 8, 15, 22), which represents a time-averaged image of the process, and at least one time-variant process model (2, 9, 16, 23), which is based on at least one time constant of a disturbance variable or a variation of parameters of the process is tuned.
