Vibrational deformations of cylindrical elastic shell structures are controlled by piezopolymer transducers; the sensors could act both as actuators and receptors. Theoretical models and experimental results are presented. The mechanical models show the control of modal structural deformations. The equilibrium equations are obtained from the Hamilton principle, using the Love Kirchhoff hypothesis. Cylindrical structures were studied in view of vibration induced protection of ship hulls against marine fouling.
