Non-interacting tension control in a multi-span web transport system
Abstract
A non-interacting tension control algorithm is proposed to reject the disturbance due to the interaction between neighboring processing sections. An 'auxiliary dynamic model' is derived. And an 'auxiliary controller' is designed with the concept of feedback and feedforward control using the auxiliary dynamic model such that it can reject disturbances from the upstream as well as down stream web span. The performance of this controller is compared with that of an existing controller. When the proposed controller is used, the tension in each span is successfully regulated even in a highly interacting multi-span system with less control effort than that of an existing control method.
