Mathematical model for virtual draft system simulation (VDSS)

The textile sliver drafting process has a decisive influence on the quality of yarn produced, and from the point of view of system theory it is marked by non-linearity, distributed delays and highly oscillatory disturbance response. As with most other textile manufacturing processes, this process has received almost no attention in control engineering literature. Motivated by the current needs of textile manufacturing, this paper introduces a suitable mathematical model of virtual draft system simulation.
