Abstract: 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 gear, if shimmy… read more here.

DOI: 10.1016/j.jsv.2018.02.036
Abstract: Abstract Eigenvalues and eigenvectors play a fundamental role in determining the dynamic behavior of a vibrating system. Thus, an important goal in vibration control is to modify the eigenstructure to match the design specifications. Feedback… read more here.

DOI: 10.1016/j.ymssp.2016.08.046
Abstract: Abstract The assignment of the eigenstructure (i.e. eigenvalues and eigenvectors) in vibrating systems is an effective way to improve their dynamic performances. System controllability ensures that the poles of the controlled system are exactly assigned… read more here.

DOI: 10.1080/00207179.2016.1236294
Abstract: ABSTRACT This paper presents the exposition of an output-lifting eigenstructure assignment (EA) design framework, wherein the available EA design degrees of freedom (DoF) is significantly increased, and the desired eigenstructure of a single-rate full state… read more here.
