A straightforward method for tuning of Lyapunov-based controllers in semi-active vibration control applications
(Elsevier, 2013-11-15)
Lyapunov-based control is an attractive strategy for semi-active vibration control as it has a mathematical basis ensuring stability in the sense of Lyapunov and great flexibility in the design. Unfortunately, that flexibility ...
Control of relative vibration between flexible appendages using passive and semi-active isolation
(Elsevier, 2017-12)
Relative vibration between two flexible subsystems can be detrimental to the performance of many engineering applications, such as optics-based instruments, machine tools, or adjacent industrial structures sharing piping. ...
Semi-active friction tendons for vibration control of space structures
(Elsevier, 2014-07)
Semi-active vibration control systems are becoming popular because they offer both the reliability of passive systems and the versatility of active control without high power demands. In this work, a new semi-active control ...
Suppression of vibrations in a nonlinear half-car model using a magneto-rheological damper
(2014)
The present work investigates the nonlinear response of a half-car model. The disturbances of the road are assumed to be sinusoidal. After constructing the bifurcation diagram, we use the 0-1 test to identify chaotic ...
An approach to reduce vibration and avoid shimmy on landing gears based on an adapted eigenstructure assignment theory
(2020-01-01)
Landing gear shimmy is a self excited vibration phenomenon which must be avoided during aircraft design due to its potentially catastrophic behaviour. In a preliminary specification of structural properties of a landing ...
On the controllers' design to stabilize ground resonance helicopter
(2019-12-01)
Ground resonance (GR) in helicopters is a potentially catastrophic instability commonly caused by coalescence of the regressive cyclic blade lag mode with the fuselage motion in certain rotor speed ranges. It can limit the ...
An Intelligent Controller Design for Magnetorheological Damper Based on a Quarter-car Model
(Sage Publications Ltd, 2009-12-01)
This paper presents the control strategies of nonlinear vehicle suspension using a magnetorheological (MR) damper. We used two different approaches for modeling and control of the mechanical and electrical parts of the ...
Using passive control by a pendulum in a portal frame platform with piezoelectric energy harvesting
(Sage Publications Ltd, 2018-08-01)
This work presents a passive control strategy using a pendulum on a simple portal frame structure, with two-to-one internal resonance, with a piezoelectric material coupling as a means of energy harvesting. In addition, ...
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 ...
