Impact of the reference model on the values of maximum dynamic error

Abstract

The paper presents the results of research into linear and time-invariant measurement systems, which are modelled by means of the second order transfer function and are intended for measurements of acceleration (accelerometers with voltage output). The maximum dynamic errors will be determined for the case of input signals with one constraint and for the integral-square and absolute criteria. The algorithms for determining input signals that maximise the error for both quality criteria are presented. The transfer functions of Butterworth, Chebyshev, and Bessel analogue filters are used as the reference model. The cut-off frequency of the filter is selected in such a way so as corresponds to the frequency response of the measurement system.
