The planetary torsional vibration absorber system includes a planetary gear system including a ring gear, a sun gear and a carrier. At least one of the ring gear, the sun gear and the carrier is rotationally fixed to the rotating component and another of the ring gear, the sun gear and the carrier is fixedly secured to the stationary component. A tuned vibration absorber including a tunable damping and stiffness component and an inertia ring is mounted to yet another of the ring gear, the sun gear and the carrier.
