The exciting force of flexural motion, which is induced by the motion of the manipulator, causes undesired deflection at the end-effector. The null space inherent in redundancy feature is exploited to damp out the vibration while maintaining the end-effector posture. In order to exploit all the degrees of freedom in the null space, a feedback control design based on torque optimization has been introduced using analytical method for the redundancy resolution. The simulation analysis is presented to test the effectiveness of the proposed approach. %G English %2 https://cea.hal.science/cea-03314681/document %2 https://cea.hal.science/cea-03314681/file/2020_IFAC_Rahmouni.pdf %L cea-03314681 %U https://cea.hal.science/cea-03314681 %~ CEA %~ ENSAM %~ DSV %~ DRT %~ CEA-UPSAY %~ TDS-MACS %~ UNIV-PARIS-SACLAY %~ CEA-DRF %~ LIST %~ UNIVERSITE-PARIS-SACLAY %~ GS-ENGINEERING %~ GS-COMPUTER-SCIENCE %~ HESAM %~ HESAM-ENSAM %~ IRENAV %~ LAMPA %~ LCPI %~ LABOMAP %~ LISPEN %~ MSMP
