Abstract

Our aim was to develop a high-speed and high-accuracy mass measurement system to be used with a conveyor belt (a checkweigher). The objective in this paper was to present a dynamic model of our proposed measurement system. The checkweigher with an electromagnetic force balance system was approximated using a spring-mass-damper system as the physical model, and the equation of motion was derived. The model parameters could be obtained from experimental data. Finally, the validity of the proposed model was confirmed by comparison of the simulation results with the experimental responses. The dynamic model obtained offers practical and useful information to examine the control scheme and to achieve high-performance mass measurement.
