    A new, simple control method for vibration absorber design is presented in this paper. A nonlinear robust control scheme based on a variable structure is designed and simulated. Robust synthesis of the discontinuity surface based on classical frequency loop-shaping and the Edge Theorem is discussed. The proposed control scheme has two advantages over the current existing vibration absorber design methodologies: (i) it is completely insensitive to changes in the stiffness and damping of the absorber, and it is strongly robust against parametric uncertainties of the primary vibrating structure; (ii) it is capable of suppressing both cyclic and random vibrations over a very wide range of frequencies.
