A decentralized controller that suppresses the vibrations of a flexible cable-stayed beam structure induced by an external random disturbance is presented. The controller is designed based on a lumped-mass model representation of the distributed parameter flexible beam structure. It contains a linear part and a nonlinear part. The linear part is used to introduce damping into the beam structure and the nonlinear part is used to further reduce the vibrations caused by the external disturbance. Its performance is assessed via digital computer simulation.
