Dynamic models of servo-driven conveyor system

This paper concerns dynamics of a servo-driven conveyor system, which has been developed for the laboratory-scale experiments. This system consists of a belt lying on the iron plate with two shafts at the end. A DC motor is used to drive the belt through the shaft. The belt is considered to behave like a nonlinear spring. We include the Lugre friction in this model. Then, the dynamics of the conveyor system are derived based on certain specified assumptions. At the same time, the linear and linearized model is used to analyze the behaviors for small signals. Finally, the time responses of these models are shown to verify the modelling analysis.
