Dynamic interaction of electric drives in a rolling mill ...

2011-6-29 · A computer model has been developed for the control of frequency-controlled drives within a rolling mill; the model takes account of the drives’ elastic interaction. The model permits adjustment of the speed-correction system for the rolling cells in the mill so as to neutralize the elastic-interaction torques. Such correction is theoretically feasible for all cells of the rolling
