A novel method of describing the dynamic behaviour of
EMC load cells is presented. This method involves Thiele–
Small parameters which give the opportunity to validate
the applicability of a load cell in terms of dynamic purposes.
The Thiele–Small parameters are easy to derive from
two simple measurements of the coupling factor lB and the
frequency response of the impedance. From these parameters,
both mechanical and electrical characteristics of the
investigated system can be derived. In this paper we
showed that, based on the Thiele–Small parameters, the
parameters of a PID controller can be obtained fully automated
from a simple algorithm. Additionally, the optimisation
of the design process of dynamic EMC load cells may
be supported by setting the optimal parameters derived
for a given application.
