Abstract

Acontrolmethod to stabilize vibration of a double cantilever systemwith a set of smart damping blocks is designed and numerically evaluated. The externally controlled magnetorheological sheared elastomer damping block is considered, but other smartmaterials can be used as well.Therobust bang-bang control law for stabilization the bilinear system is elaborated.The key feature of the closed loop controller is the efficiency for different types of initial excitement. By employing the finite element model, the performance of the controller is validated for strong wind blow load and concentrated impact excitement of the particular point of one of the beams. For each of the excitations, the closed loop control outperforms the optimal passive damping case by over 27% for the considered energy metric.
