Suppression of Oscillations by Lévy Noise [PDF]

open access: yesUkrainian Journal of Physics, 2022
We find the analytic solution of a pair of stochastic equations with arbitrary forces and multiplicative Lévy noises in a steady-state nonequilibrium case. This solution shows that Lévy flights always suppress a quasiperiodic motion related to the limit cycle.

Suppression of burst oscillations in racing motorcycles [PDF]

open access: yes49th IEEE Conference on Decision and Control (CDC), 2010
Burst oscillations occurring at high speed, and under firm acceleration, can be suppressed with a mechanical steering compensator. Burst instabilities in the subject racing motorcycle are the result of interactions between the wobble and weave modes under firm-acceleration at high speed.

Self-sustained oscillations with delayed velocity feedback [PDF]

open access: yesPapers in Physics, 2017
We study a model for a nonlinear mechanical oscillator, relevant to the dynamics of micro- and nanomechanical time-keeping devices, where periodic motion is sustained by a feedback force proportional to the oscillation velocity.
