Elastic web processing lines : optimal tension and velocity closed loop bandwidths

نویسنده

  • D. Knittel
چکیده

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 influence of the tension and velocity bandwidths is studied.

The Effect of Speed Loop Bandwidths and Line-Speed on System Natural Frequencies in Multi-Span Strip Processing Systems

Strip Processing systems (SPS’s) are composed of multiple tension zones. These zones are separated by driven rolls such as bridles whose speed is regulated by a closed loop controller. Given that the typical tension regulator regulates tension by trimming the reference to a closed speed loop controller, the designer of the tension regulator cannot ignore the effects of closing the speed loop, a...

H∞-based PI-observers for web tension estimations in industrial unwinding-winding systems

The system under study is a web handling machine composed of an unwinder, several traction motors, several idlers with or without load cells and a winder. All flexible materials such as textiles, papers, polymers or metals are handled on rollers during their processing. Maintaining strip tension in the entire processing line while increasing web speed is a key factor for achieving good final pr...

A Feed-forward Tension Control in Drying section of Roll to Roll e-Printing Systems

The mathematical model for tension behaviors of a moving web by Shin (Shin, 2000) is extended to the tension model considering the thermal strain due to temperature variation in a dryer of the roll to roll systems. The extended model includes the terms that take into account the effect of the change of the Young’s Modulus, the thermal coefficient, and the thermal strain on the variation of tens...

A Corotational Elastic Constitiutive Model and its Application to the Analysis of a Large Deformation Closed Cycle

In this paper, an elastic constitutive model based on the Eulerian corotational rate of the logarithmic strain tensor is proposed. Using this model, the large deformation of a closed cycle containing tension, shear, compression and inverse shear is analyzed. Since the deformation path includes a closed cycle and the material is considered as an isotropic elastic material, the normal and shear c...
