“…The input tension was calculated using the SCADA system and the output tension was calculated with a tension controller. Synthesis of the tension controller itself can be found in our previous work [11]. T1 to T5 are the reference tension values acting as dynamic saturations at the outputs of the speed PI controllers of The algorithm requires knowledge of the values of input tension F IN = F 01 and the desired output tension F OUT = F 56 and calculates reference tension values of T 1 to T 5 .…”

“…The proper control algorithm for tension distribution among the bridle rolls must ensure precise elongation control of the strip and balanced loading of the roll drives. The following approaches are used for strip tension control: indirect tension control by speed difference of the rolls [10], speed with torque limit tension indirect control [11,12], tension control by utilization of tension sensors [13][14][15][16][17], and sensorless tension control [18][19][20][21]. A detailed review of all these control approaches can be found in [22].…”

The control of tension in processing lines for metal strips tackles several problems. The process of achieving high tension driven by a multi-motor drive system, where the motors are mechanically coupled by a strip, is affected by the maximal torque of each drive, by friction between the strip and the surface of the tension roll, and by the wrap angle. The friction itself and the wrap angle are described by the e µα factor, which can be also calculated as the ratio of tensions in the strip in the previous section and subsequent section of the multi-motor drive. In this paper, an algorithm for the proper distribution of tensions in the strip for a multi-motor drive system of a continuous processing line is revealed. The algorithm ensures the tension distribution among particular drives of the tension leveler while respecting the physical limits of the drives and also preserving the desired conditions of a constant ratio between the input and output tensions for all drives in the leveler. The algorithm also prevents overloading of the drives. Finally, the algorithm was implemented in a control system of a strip processing line, and the obtained results correspond with the simulations. This, in turn, confirms the correctness of the algorithm design.
