Adaptive feedforward based control strategy for attenuation of periodic tension oscillations in roll-to-roll manufacturing
(Oklahoma State University, 2013-06)
Considering the aforementioned issues, an adaptive feedforward (AFF) algorithm that can work in parallel to an existing feedback control systems is developed for control of web tension and to attenuate periodic oscillations. ...
On the governing equation for web tension with out-of-round rolls
(Oklahoma State University, 2013-06)
In roll-to-roll (R2R) manufacturing the presence of non-ideal elements, such as out-of-round or eccentric rolls, induces periodical oscillations in the web tension signal. Model simulations based on ideal elements do not ...
