我们的目标是开发一种与传送带（检重秤）配合使用的高速、高精度质量测量系统。本文的目的是提出我们提出的测量系统的动态模型。采用弹簧-质量-阻尼器系统作为物理模型对带有电磁力平衡系统的检重秤进行了近似，并推导了运动方程。模型参数可以从实验数据中获得。最后，通过仿真结果与实验响应的比较，证实了所提出模型的有效性。获得的动态模型为检查控制方案和实现高性能质量测量提供了实用且有用的信息。
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.
