Abstract in different language:	This paper describes one of the functional methods for two-mass system torsional vibrations suppression that are evoked due to torsion plasticity of kinematical chain links and large moment of inertia. This strategy belongs to the group of feedback methods. To its function, the method uses a mathematical model of mechanism to predict the actual speed of the kinematical chain working link. By means of that signal, the measured motor shaft actual speed and weightings product the required correction signal which is able to significantly damp the torsional vibrations of the kinematical chain end-link. The control structure was tested by simulation and then integrated into the existing cascade structure standard servo control unit Siemens Sinamics S120. The results of the simulations on the two-mass system mathematical model and the experiments on the real device demonstrated the ability of this method to effectively compensate the torsional vibrations of the mechanism end-link.
