Distributed Piezoelectric-Polymer Active Vibration Control of a Cantilever Beam
Thomas Bailey,James E. Hubbard +1 more
TL;DR: In this article, an active vibration damper for a cantilever beam was designed using a distributed-parameter actuator and distributedparameter control theory, and preliminary testing of the damper was performed on the first mode of the beam.

Patient activity monitor
TL;DR: A patient activity monitoring system that allows caregivers of multiple patients to work more efficiently and with reduced cost, while increasing the quality and level of patient care is described in this article, which includes a plurality of remote monitoring subsystems, user notification units, and a central monitoring unit with a Graphical User Interface (GUI) communicably coupled between the remote monitoring and user notifications units.
Journal ArticleDOI
Active vibration control of a simply supported beam using a spatially distributed actuator
Shawn E. Burke,James E. Hubbard +1 more
TL;DR: In this article, a spatially shaped distributed actuator for the vibration control of a simply supported beam is studied both analytically and experimentally, with emphasis on how controllability requirements affect the choice of the film's spatial distribution.
Journal ArticleDOI
Nonlinear Control of a Distributed System: Simulation and Experimental Results
TL;DR: In this paper, a nonlinear active vibration damper was developed which uses a spatially distributed piezoelectric actuator, polyvinylidene flouride, to achieve active vibration control of a cantilever beam.
Journal ArticleDOI
Distributed actuator control design for flexible beams
Shawn E. Burke,James E. Hubbard +1 more
TL;DR: 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.
