MATHEMATICAL MODEL OF CHECKWEIGHER WITH ELECTROMAGNETIC FORCE COMPENSATION
Y. Yamakawa, T. Yamazaki
Abstract:
In this research we develop a high speed mass measurement system with conveyor belt (a checkweigher). The objective in this paper is to propose a dynamic model of the measurement system. The checkweigher with electromagnetic force compensation can be approximated by the spring-mass-damper systems as the physical model, and an equation of motion is derived. The model parameters can be obtained from the experimental data. Finally, the validity of the proposed model can be confirmed by comparison of the simulation results with the realistic responses. The dynamic model obtained offers practical and useful information to examine control scheme.
