The invention relates to dynamic vibration absorbers and can be used in movable autonomous objects, for instance ships, aircrafts. A controlled dynamic vibration absorber has damping mass suspended on springy elements fixed on the body. According to the invention, as elastic elements there are used elements with non-linear characteristic of rigidity part of which at one end is fixed on the damping mass and at the other end on the body, the others are fixed at one end on the damping mass and at the other end on the movable beam. The beam is fixed on the body with possibility of displacement along the axis of elastic elements by means of controlled drive. The invention makes it possible to absorb effectively vibration in broad range of frequencies and amplitudes with decrease of overall dimensions of the construction.
