Abstract

In this paper a mechatronic model for an electromagnetic-force-compensated (EMC) load cell is presented. Designed in MATLAB® Simulink® the model consists of four main modules: a rigid-body model delineating the mechanical behaviour of the load cell, an analytical model characterising the electrodynamic actuator consisting of a voice coil and a permanent magnet, a characteristic curve modelling the position detector, and a continuous or discrete model describing the operation of the controller. <br />Optimization of the mechanical, electromagnetic and controller components can be performed using this model; furthermore experiments can be performed to determine the sensitivity of the complete system to changes of defined parameters.
