Vibration control in truss structures using piezoelectric stack actuator and LMI approach
(2008-01-01)
The recent years have seen the appearance of innovative system for acoustic and vibration attenuation, most of them integrating new actuator technologies. In this sense, the study of algorithms for active vibrations control ...
Active vibration control using delayed resonant feedback
(2013-09-01)
Delayed feedback (DF) control is a well-established technique to suppress single frequency vibration of a non-minimum phase system. Modal control is also a well-established technique to control multiple vibration modes of ...

Novel active and passive anti-vibration mountings
(Academic Press Ltd Elsevier B.V. Ltd, 2012-03-26)
This paper investigates a novel design approach for a vibration isolator for use in space structures. The approach used can particularly be applicable for aerospace structures that support high precision instrumentation ...
Análise da resposta dinâmica de um sistema mecânico com amortecedor de massa passivo: um estudo experimental e numérico
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em Engenharia CivilUTFPR, 2018-05-30)
Dynamic vibration control is fundamental in noise reduction and structural vibration caused by external loads. If the vibration is excessive it can compromise the physical integrity of the structure, through a fatigue ...
Narrowband feedback for narrowband control of resonant and non-resonant vibration
(2016-08-01)
This paper presents a simple feedback methodology that uses second order filters to control narrowband resonant and non-resonant vibration of a structural system. In particular, a single degree-of-freedom system is studied ...
Optimal design of smart structures using bonded piezoelectrics for vibration control
(2000-12-01)
Smart material technology has become an area of increasing interest for the development of lighter and stronger structures which are able to incorporate actuator and sensor capabilities for collocated control. In the design ...
