On saturation control of a non-ideal vibrating portal frame foundation type shear-building
(Sage Publications Ltd, 2005-01-01)
In this paper, we examine the nonlinear control method based on the saturation phenomenon and of systems coupled with quadratic nonlinear ties applied to a shear-building portal plane frame foundation that supports an ...
Nonlinear piezoelectric vibration energy harvesting from a portal frame with two-to-one internal resonance
(2017-09-01)
In the few decades, the study of electro-mechanical systems which are capable to extract energy from an operating system in the environment has been of most importance. In this work, we present the extraction of energy ...
Short comments on self-synchronization of two non-ideal sources supported by a flexible portal frame structure
(Sage Publications Ltd, 2004-12-01)
A practical problem of synchronization of a non-ideal (i.e. when the excitation is influenced by the response of the system) and non-linear vibrating system was posed and investigated by means of numerical simulations. Two ...
On suppression of chaotic motions of a portal frame structure under non-ideal loading using a magneto-rheological damper
(2015-01-01)
We consider chaotic motions of a portal frame structure under non-ideal loading. To suppress this chaotic behavior, a controlling scheme is implemented. The control strategy involves application of two control signals and ...

Modeling and experimental validation of two adjacent portal frame structures subjected to vibro-impact
(2019-03-27)
In many engineering applications, there are systems that exhibit a series of collisions in a certain amount of time, for example the impact of floating ice in ships and the rubbing between stationary and rotary parts in ...
On an energy exchange process and appearance of chaos in a non-ideal portal frame dynamical system
(2013)
In this paper, we consider non-ideal excitation devices such as DC motors with restrictenergy output capacity. When such motors are attached to structures which needexcitation power levels similar to the source power ...
A non-ideal portal frame energy harvester controlled using a pendulum
(2013-09-01)
A model of energy harvester based on a simple portal frame structure is presented. The system is considered to be non-ideal system (NIS) due to interaction with the energy source, a DC motor with limited power supply and ...
Comments on energy harvesting on a 2:1 internal resonance portal frame support structure, using a nonlinear-energy sink as a passive controller
(2016-01-01)
This paper presents an application of a passive control strategy in a base-excited two-degrees-of-freedom portal frame support structure considering extract energy using a piezoelectric material coupled to a column. The ...
