Summary:This paper deals with the problem of mechanical resonance in
modern servo drive systems having the speed control loop bandwidth and
resonance frequency above 100 Hz. To enable the extension of the range
of stable gains in the presence of flexible coupling, a simple and
straightforward modification of the speed loop controller is proposed in
order to augment the performance of present speed controllers and to
make them accordant with mechanical structure suffering from the
compliance problem. This paper is comprised of the analytical
considerations, straightforward design guidelines, and results of
experimental verification obtained by an experimental setup with the
elastically coupled 7-N m synchronous servo motor and mechanical
resonance frequency of 160 Hz
