Optimal placement and tuning of pointwise dampers for vibrating strings via a Lyapunov framework
Josip TambaÄa, Ninoslav Truhar
We study the optimal placement and tuning of a small number of pointwise viscous dampers for a vibrating string. Starting from a finite element discretization of the damped wave eq…
Structure-preserving deflation of critical eigenvalues in quadratic eigenvalue problems associated with damped mass-spring systems
Rafikul Alam, Volker Mehrmann, Ninoslav Truhar
For a quadratic matrix polynomial associated with a damped mass-spring system there are three types of critical eigenvalues, the eigenvalues and and the eigenvalues on…
An adaptive scheme for the optimization of damping positions by decoupling controllability spaces in vibrational systems
Jennifer Przybilla, Matea Ugrica VukojeviÄ, Ninolsav Truhar +1
In this work, the problem of optimizing damper positions in vibrational systems is investigated. The objective is to determine the positions of external dampers in such a way that…
Damping optimization of discrete mechanical systems -- rod/string model
Ninoslav Truhar, KreÅ¡imir VeseliÄ
This paper investigates two optimization criteria for damping optimization in a multi-body oscillator system with arbitrary degrees of freedom (), resembling string/rod free vib…
