| Abstract: | The vibration control for multiple mode of structure based on piezoelectric damping technique is discussed . In theory, the blocking circuit for the energy conversion technique and its optimized circuit are described. A two-mode shunt circuit is designed and implemented for an experimental supported cantilever beam. It is shown that the two vibration modes of the structure are reduced simultaneously and the better result is obtained. |
