Abstract
This paper deals with cluster control to suppress structural vibrations occurring on viaduct roads because of vehicles' ride on them. A viaduct road has been modeled using finite element method to obtain the structural modes. Based on the finite element model of the flat road part, a cluster control method is introduced. The modes of flat viaduct road have been classified in four groups at first. Each group has been controlled separately using sliding mode controller (SMC). The control action is realized using cluster actuation. It is verified that cluster actuation and sensing based on SMC suppress considered structural modes without observation of spillover effects.
