SYSTEM IDENTIFICATION OF FORCE TRANSDUCERS FOR DYNAMIC MEASUREMENTS

Alfred Link, Bernd Glöckner, Christian Schlegel, Rolf Kumme, Clemens Elster
Abstract:
Knowledge of the transfer function of a force transducer is required in order to determine a transient force from the transducer's output signal. We describe a linear least-squares fit method for system identification to estimate the transfer function from sinusoidal force calibration measurements, and we consider the evaluation of uncertainty associated with the obtained estimate. In applying this method to different calibration measurements it is demonstrated that consistent results are obtained for the transfer function.
