Elastic Web Processing Lines: Optimal Master Roller Position

Kevin Lifsey

Presented by D. Knittel, Institute of Physics and Engineering

This paper concerns the tension control of roll-to-roll systems. In such systems, each driven roller speed is controlled separatly. The impact of the master roller position on tension control performances is studied using optimized web tension control synthesis. The tension disturbance rejection property and the system robustness regarding web elasticity variations are analysed for each configuration. Then the bandwidth influence of the driven roller speed control is studied.
