Decentralized model reference control of flexible cable-stayed beam structures

A decentralized model reference controller is designed to reduce the magnitude of the transversal vibration of a flexible cable-stayed beam structure induced by a seismic excitation. The controller design is made based on the principle of sliding mode such that a priori knowledge on the bounds of the uncertainties and disturbances is not required. A numerical simulation example is presented to illustrate the effectiveness of the proposed control scheme for a scaled model of a bridge
