Graduate student seminar | Disturbance rejection from the lateral motion in a roll-to-roll web system

Speaker

Abstract

In a roll-to-roll web system, lateral motion of a web caused by disturbances, which are often periodic, results in poor product quality. To reduce the effect of such disturbances, two existing control strategies are used. The first uses the internal model principle for sinusoidal disturbances with known period, and the second uses repetitive control theory for general periodic disturbances with known period. In this talk, I will review both strategies and then apply them on a five roller web system.
