“…Strain sensors in the previous sense are also known under the notion of spatial filters (as they filter certain spatial information. Examples are modal filters (Lee and Moon [94]), displacement filters (Krommer and Irschik [89]) and volume displacement filters (Preumont et al [95]). Spatial filters are used for structural control and structural health monitoring (e.g., Deraemaeker and Preumont [96]), and they can be put into practice by piezoelectric transducers; e.g., refs.…”

Structural control has been comprehensively studied over the world as a multidisciplinary research field. The present work is motivated by an attempt to give a common frame to the recent research and applications of structural control technology in civil engineering across Europe. They include novel passive dampers, functional materials and semi-active dampers, active control systems, and their performance investigations. Design methods for the vibrations reduction of buildings, bridges, and wind turbines are discussed with reference to case studies. Control algorithms and dimension reduction techniques are also studied. Adaptation strategies and techniques based on the potential offered by piezoelectricity are reviewed

“…To remedy such a situation, this paper continues to develop distributed control for non-Fourier heat conduction, inasmuch as distributed sensors and actuators are well-developed nowadays [3][4][5][6][7][8][9][10][11][12][13][14]. Distributed control is capable of tracking precise local-temperatures with slow heating over the entire region of heat conduction, which is otherwise beyond the nature of pointed control.…”

Abstract:In a previous study we provided analytical and experimental evidence that some materials are able to store entropy-flow, of which the heat-conduction behaves as standing waves in a bounded region small enough in practice. In this paper we continue to develop distributed control of heat conduction in these thermal-inductive materials. The control objective is to achieve subtle temperature distribution in space and simultaneously to suppress its transient overshoots in time. This technology concerns safe and accurate heating/cooling treatments in medical operations, polymer processing, and other prevailing modern day practices. Serving for distributed feedback, spatiotemporal μ / ∞ H control is developed by expansion of the conventional 1D-μ / ∞ H control to a 2D version. Therein 2D geometrical isomorphism is constructed with the Laplace-Galerkin transform, which extends the small-gain theorem into the mode-frequency domain, wherein 2D transfer-function controllers are synthesized with graphical methods. Finally, 2D digital-signal processing is programmed to implement 2D transfer-function controllers, possibly of spatial fractionorders, into DSP-engine embedded microcontrollers.

“…A well known approach is based on the ''radiation modes'' concept; it was shown 10,11 that the sound power can be written in terms of radiation modes, which correspond to the eigenvectors of the radiation impedance operator of the structure and radiate sound independently. Some literatures discussed shaped PVDF sensors for estimating the acoustic power modes 12 or modal amplitudes of a two-dimensional plate 13,14 . Snyder et al 7,15 have implemented the active control of sound radiation from a simply supported panel using PVDF film shaped in order to observe the radiation modes of the panel.…”

This paper presents a new volume velocity sensor and its application in active structural acoustic control system. Utilizing the charge output equation of the PVDF piezoelectric film and orthogonal property of trigonometric function, a design strategy for a PVDF sensor detecting the volume velocity induced by a vibrating 2D structure is presented. The designed sensor is made of shaped strips of PVDF film. The experimental implementation of the new sensor in an active structural acoustic control system is then presented. The experimental results obtained validate this new type of volume velocity sensor, and significant attenuation of the radiated sound field is obtained.
