“…The signal of the received sound is then used in a feedback system that controls an actuator which tries to attenuate the sound in real time by generating a destructive signal that opposes the surrounding noise. For this purpose, in many cases sensing/acting PZTp have been used in passive/active sound absorbers [ 52 , 54 , 55 , 56 , 57 , 61 , 62 , 63 , 64 , 65 ]. A schematic of a passive/active sound absorber scheme is shown in Figure 5 .…”

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.

“…At the specific point of the beam, i.e., a i1 or a i2 , the normal function φ 1 (a i1 ) or φ 1 (a i2 ) is a constant. As a result, equation (22) can be rewritten as where C 11 and C 21 are constant. Then, the control law (16) becomes…”

“…In recent years, the use of smart piezoelectric materials for actuation has grown in vibration damping [16][17][18][19][20][21][22][23][24][25]. The majority of smart actuator controls in the literature utilized feedback of the angular velocity at the actuator's location and was designed based on relative easy stability analysis.…”

In this paper, a hybrid control algorithm is proposed to control the rotation of a flexible beam while suppressing the beam's vibration. The control law combines an enhanced PD feedback with a nonlinear differentiator to derive a high-quality velocity signal to control the gross motion of the beam, and a vibration control by PZT actuators bonded on the surface of the beam. There are three advantages of the proposed method: (i) the enhanced PD control is model free, and appears to be more robust against the noise; (ii) the linear velocity rather than the angular velocity is used in the PZT actuator control, a signal which is easily available; (iii) a unique solution is provided for examination of the actuator placement, based on the analysis of mode shape functions. Experimental results validate these theoretical analyses.

“…As modelling and control aspects began to assume prominence, a cantilevered beam was used as the basis of a study by Baz [38] to illustrate the e ectiveness of a variational model in conjunction with boundary control. An alternative approach was described by Rongong and his colleagues [39], whereby mathematical models of a cantilevered beam, derived using a Rayleigh-Ritz approach, were validated in a comprehensive experimental study. Papers by Liao and Wang [40] and Liu and Wang [41] used a cantilevered beam to demonstrate the advantages of augmenting the piezoelectric layer by edge elements.…”

In this paper the authors discuss the progress that has been made over the past decade in active constrained-layer damping (ACLD). ACLD treatments combine the best features of passive and active control of structural vibrations. By way of introduction the paper describes well-established techniques for passive control of structural vibrations and noise. A concise discussion of the development of so-called 'smart' (or 'intelligent') actuators and sensors and the emergence of suitable control algorithms show how passive techniques were extended to produce ACLD. A comprehensive literature review follows. It is shown how the passive and active components of ACLD complement each other to enable control of both high and low frequency modes of vibration. The active elements allow structures to adapt to suit a changing environment while the passive elements provide a fail-safe mechanism. Because of the available technology, these bene ts are available without signi cant penalties in terms of cost, weight and complexity.
