Simplified inverse control method for two-mass servomechanism vibration suppression

This paper describes a functional method for a two-mass system residual vibration suppression. This vibration is induced due to the torsion plasticity and high inertia parts of servomechanism kinematical chain. The main principal of this method is in using the inverted servomechanism transfer function as a controller. But because of quite limited resources of standard servo-controllers control structure and almost no possibility for performing any fundamental changes in theirs control structure, the inverse model have to be simplified. As it was proven experimentally this simplification has no effect on residual vibration suppression.
