“…A variety of techniques to examine the sound radiation from slender bodies of revolution and spheroidal shells have often been developed with application to submarine hulls [15][16][17][18][19][20][21][22][23][24][25][26]. Recently, Pan et al [27,28] studied an active control strategy to reduce the sound radiation from an axisymmetrically vibrating submarine vessel with conical and spherical end caps.…”

“…Regarding submerged cylindrical shells, Pan et al [ 45 ] numerically analyzed the reduction of the radiated pressure of a cylindrical shell type structure (submarine hull) by reducing the structural vibrations in the axial direction (low frequency modes). In both cases, PZTp are circumferentially mounted.…”

Submerged systems are found in many engineering, biological, and medicinal applications. For such systems, due to the particular environmental conditions and working medium, the research on the mechanical and structural properties at every scale (from macroscopic to nanoscopic), and the control of the system dynamics and induced effects become very difficult tasks. For such purposes in submerged systems, piezoelectric patches (PZTp), which are light, small and economic, have been proved to be a very good solution. PZTp have been recently used as sensors/actuators for applications such as modal analysis, active sound and vibration control, energy harvesting and atomic force microscopes in submerged systems. As a consequence, in these applications, newly developed transducers based on PZTp have become the most used ones, which has improved the state of the art and methods used in these fields. This review paper carefully analyzes and summarizes these applications particularized to submerged structures and shows the most relevant results and findings, which have been obtained thanks to the use of PZTp.

“…By inserting equation (12) into equation (1), the equation of motion of the cylindrical shell in conjunction with piezoelectric disks is obtained as (18) (19) (20) It is supposed that no external voltage is applied to the sensors (V se = 0), thus, the electrical charge of the sensors and actuators can be derived from equations (19) and (20). (21) (22) By substituting equations (21) and (22) …”

“…Pan et al [17] theoretically analysed the active control of low-frequency radiated pressure from a finite cylindrical pressure hull using control action through a Tee-sectioned circumferential stiffener driven by a pair of PZT stack actuators. The same work is carried out in [18] on a more complicated model with a hemispherical shell at one end and a conical shell at the other end. Cao et al [19] actively controlled the sound pressure radiated from a cylinder by controlling the axial low-frequency vibration of a shell using stack piezoelectric actuators.…”

Active vibration control of a cylindrical shell using piezoelectric disks is studied both theoretically and experimentally in this paper. Hamilton's principle is used for deriving dynamic motion equations of the cylinder coupled with piezoelectric disks. The equations are discretised by Rayleigh-Ritz method. An adaptive feedforward controller based on steepest descent method is implemented on a PC to control the modal vibration. The proposed method solves the drawback of using PCs that is sending and receiving data in block form. It is shown that the proposed control system which consists of piezoelectric disks and an adaptive controller is effective in reducing vibration and radiated acoustic noise.
