Abstract

A method for controlling a treatment process of a medium that includes a system input and output, wherein a change in a first parameter of the medium at the system input causes a change in a second parameter at the system output only after an elapse of a dead time, and a control system, the method including determining first values of the first parameter; determining set values for an output variable influencing the second parameter at the system output using the determined first values and a first proportionality factor recorded in the control system; applying the determined set values to adjust the output variable; determining second values of the second parameters; determining deviation values representative of a deviation of the second parameter from the first parameter; and using at least one of the deviation values and at least one of the set values to determine a second proportionality factor.
