Robust control applications for smart truss structure
(2005-12-01)
A finite element modeling of an intelligent truss structure with piezoelectric stack actuators for the purpose of active damping and structural vibration attenuation is presented. This paper concerns with the following ...
System Identification and active modal control of a flexible truss structure
(2015-01-01)
The aim of this paper is to illustrate the active control of vibration of a flexible truss structure using a model-based digital controller. The state-space model of the system is derived using a system identification ...
Passive control applied to structural optimization and dynamic analysis of a space truss considering uncertainties
(Katholieke Univ Leuven, Dept Werktuigkunde, 2016-01-01)
Due to the need for monitoring Earth's natural systems, fleets of satellites will be launched in the next few years. In order to minimize shuttle launch costs, space structures should have the shape of trusses because of ...

Using of a snap-through truss absorber in the attenuation of the sommerfeld effect
(E D P Sciences, 2012-01-01)
This work, considers a vibrating system, which consists of a snap-through truss absorber (STTA) coupled to an oscillator, under excitation of an DC motor, with an eccentricity and limited power, characterizing a non-ideal ...
A finite element approach for predicting the ultimate rotation capacity of RC beams
(2013-07-15)
This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...
Optimal placement of sensors/actuators in truss structures with known disturbances
(2006-12-01)
An important stage in the solution of active vibration control in flexible structures is the optimal placement of sensors and actuators. In many works, the positioning of these devices in systems governed for parameter ...
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 ...
