Abstract :
The paper deals with the identification and damping of torsional oscillations in high dynamic industrial drives. Based on a model with two concentrated masses with an elastic coupling and driven by a field-orientated induction machine, methods for the identification and damping of torsional oscillations were developed. On a downscaled laboratory setup, well-known and newly developed procedures for the identification of the resonance frequencies were compared regarding their effectiveness and effort of implementation and under consideration of an automatic identification. Besides, experimental results of several methods for the active damping of the torsional oscillations are presented. They were completed by measurements carried out on a high dynamic industrial drive for a cross cutter for paper (sheeter)
