Abstract (en)

[origin: WO2014198493A1] The invention relates to a method for calibrating or for adjusting any oscillatable unit by means of a mathematical model (model) which describes the oscillatable unit, wherein the oscillatable unit interacts at least intermittently with a medium located in a container. According to the invention the oscillatable unit is stimulated to oscillation by means of a real input signal; the real output signal of the oscillatable unit is ascertained; the real output signal is digitised and a real output sequence (yu(k)) is generated; the real input signal is digitised and a digital input sequence (u(k)) is generated; the digital input sequence (u(k)) is supplied to a function block (model) which in interaction with the medium provides the mathematical model (model) of the oscillatable unit defined by at least two sensor-specific variables (G1, G2); a virtual output sequence (ym(k)) is generated by means of the mathematical model (model); the virtual output sequence (ym(k)) is compared to the real output sequence (yu(k)); in the event of a deviation (e(k)) the sensor-specific variables (G1, G2) of the mathematical model (model) are adaptively modified, until the deviation between the virtual output sequence (ym(k)) and the real output sequence (yu(k)) of the oscillatable unit lies within a predetermined tolerance range.
