MODEL PARAMETER IDENTIFICATION FROM MEASUREMENT DATA FOR DYNAMIC TORQUE CALIBRATION

Abstract

For the dynamic calibration of torque transducers, a model of the transducer and an extended model of the mounted transducer with the measuring device have been developed. The dynamic behaviour of a torque transducer is described by model parameters. This paper describes the model with the known and unknown parameters and how the calibration measurements are going to be carried out. The principle for the identification of the transducer’s model parameters from measurement data is described using a least squares approach.
