The combustion engine produces huge rotational periodic vibrations that could affect the acoustic comfort of the vehicle. An isolating device is placed after the engine and filters the oscillations in order to deliver a clean averaged torque to the rest of the drive train. The centrifugal pendulum is widely used even though its passive version can quench only one order of vibration. We propose in [3] a design allowing to control the tuning of the pendulum. An actuator delivers an additional force that completes the centrifugal force. This is equivalent to changing the stiffness of a classical vibration absorber. In this paper, we apply to the stiffness an optimal feedback control on a neighbouring extremal path as defined in [1]. (© 2010 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
