Abstract

A method for determining and or monitoring at least one process- and/or system specific parameter in automation technology. An oscillatable system is provided, which interacts with a medium located in a container, wherein the oscillatable system is excited to oscillate via a real input signal, wherein the real output signal of the oscillatable system is ascertained, wherein the real output signal is digitized and a real output sequence yu(k) is produced. The real input signal is digitized and a digital input sequence (u(k)) is produced, wherein the digital input sequence (u(k)) is fed to a function block (model), which provides at least one mathematical model of the oscillatable system in interaction with the medium. The mathematical model is defined by a number of process- and/or system specific parameters, wherein via the mathematical model a virtual output sequence (ym(k)) is produced, wherein the virtual output sequence ym(k) is compared with the real output sequence yu(k). In the case of a deviation, at least one process- and/or system specific parameter of the mathematical model is adaptively changed, until the deviation between the virtual output signal and the real output s…
