TLDR
In this paper, the authors proposed a non-centralized IFF control strategy to increase the implementation efficiency of a plate-based control system, not only in terms of induced damping and signal magnitudes, but also in the sense that the best designed system can be coupled with a noncentralized approach.Abstract:
Collocated IFF control strategy is commonly used thanks to its strong quality of robustness, which is due to its intrinsic damping property. Up to now, the extensive studies available in the literature have focused only on the obtained mechanical efficiency in terms of modal damping ratios. We propose here to exhibit some mechanical design parameters allowing one to really optimize this dissipation strategy, not only in terms of induced damping, but also in terms of control signal magnitudes. We apply our criterion to two different plate systems to emphasize the effects of such design variables on the control implementation. At the end, we demonstrate how the best designed system can be coupled with a non-centralized approach to increase the implementation efficiency. Copyright © 2004 John Wiley & Sons, Ltd.read more

Wave Motion Optimization in Periodically Distributed Shunted Piezocomposite Beam Structures
Abstract: This article proposes a new, simple, and efficient strategy, allowing one to optimize the diffusion operator between a passive beam coupled to a like beam equipped with a periodically distributed network of shunted piezoelectric patch actuators. A multimodal wave dispersion model is used to compute the diffusion operator and analyze the stability properties of the combined system. Based on this mathematical tool, specific optimization procedures are introduced to allow maximization or minimization of the wave transmissibility between the passive and the active distributed beam. A specific example is used to demonstrate the capability of the shunted piezoelectric system to induce total reflection through the total absorption of incoming propagating flexural waves while guaranteeing the stability, robustness, and realizability of such a system.

Feedback control of flexible systems
TL;DR: In this paper, a feedback controller is developed for a finite number of modes of the flexible system and the controllability and observability conditions necessary for successful operation are displayed, and the combined effect of control and observation spillover is shown to lead to potential instabilities in the closed-loop system.
