TLDR
Investigation of the application of a piezoelectric film actuator to the active vibration control of beams is investigated for general boundary conditions and non-uniform film spatial distributions, demonstrating that, while for most boundary configurations a spatially uniform control is appropriate, pinned-pinned, free-free,Clamped-sliding and clamped-clamped beams require non- uniform spatial distributions to be controllable.About:

Shape Control of Composite Plates and Shells with Embedded Actuators. I. Voltages Specified
TL;DR: In this article, the changes in shapes of fiber-reinforced composite beams, plates, and shells affected by embedded piezoelectric actuators were investigated, and an analytical method was developed which can be used to calculate the change in shapes for specified applied voltages to the actuators.

An Introduction to Fourier Analysis and Generalized Functions.
R. A. Kunze,M. J. Lighthill +1 more
TL;DR: The theory of generalised functions and their Fourier transforms is discussed in this paper. But the analysis of Fourier transform is limited to the case of generalized functions, and it is not suitable for generalised function analysis.
Journal ArticleDOI
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.
Journal ArticleDOI
Active control of flexible systems
TL;DR: In this paper, the authors consider the class of flexible systems that can be described by a generalized wave equation, which relates the displacementu(x,t) of a body Θ in 3D space to the applied force distribution.
