... the optimal parameter composition. Finally, three numerical case studies are prepared to demonstrate the benefits of the DRV compared with the classic DR. In addition to extending the operable frequency range of the classic DR, this work simplifies the stability analysis of the existing DR investigations...

... that a controller based on the dynamic friction model is slightly more robust to time delay (critical delay of 0.1169 s versus 0.1069 s ). Both are more robust than a controller based on a simple viscous friction model (critical delay of 0.062 s ( 16 )). The linear stability analysis...
