Extended Torsional Delayed Resonators as Applied to Reduce Driveline Vibrations
This study presents a new perspective to reduce automotive driveline vibrations. Active vibration dampers, namely torsional Delayed Resonators, are used instead of the classical approach to control the engine torque. Delayed Resonators are known to have a limited operable frequency range due to stability issues. Therefore, a new feedback strategy is introduced to the torsional Delayed Resonators in order to extend the operable frequency range of the method. The performance and the efficiency of the proposed approach is evaluated through stability analysis and system simulations.
