Suppression of chaotic oscillations in klystron active oscillator
2008 IEEE International Vacuum Electronics Conference, 2008This work presents results of an experimental investigation of the effect of suppressing chaotic oscillations in a five-resonance klystron active oscillator with delayed feedback by external harmonic signal and applying of this effect to generating a periodic sequence of chaotic radio pulses.

Phase noise suppression in LC oscillators: Tutorial
International Journal of Circuit Theory and Applications, 2021AbstractThis paper presents a comprehensive study of phase noise (PN) suppression in LC‐tank oscillators. The goal of this study is to provide designers with the latest techniques for reducing PN in cross‐coupled oscillators. To this end, we begin with a discussion of two prevalent PN models in oscillators: Hajimiri and Demir.

Ill-matched timescales in coupled systems can induce oscillation suppression.
Chaos, 2021We explore the behavior of two coupled oscillators, considering combinations of similar and dissimilar oscillators, with their intrinsic dynamics ranging from periodic to chaotic.

Suppression of Unstable Oscillations in a Boundary Layer
Fluid Dynamics, 1987A theoretical study is made of the excitation of Tollmien — Schlichting waves by a mechanical vibrator or thermal source that heats a small part of a surface in subsonic stream. According to results of most practical concern, it is possible to reduce essentially the amplitude of forced oscillations and even to attain their full attenuation by changing ...

A novel approach to suppression of oscillations
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2017AbstractWe propose a novel method of determining the control force that brings a mechanical system with finite degrees of freedom from one phase state into another one in a given time. When a system is brought from an available phase state into a prescribed state of rest we can speak about the oscillation suppression. Horizontal motion of a cart with s

A Design and Analysis of RCD Oscillation Suppression Circuit for Marx Pulse Generator
IEEE Transactions on Plasma ScienceMarx circuit is widely used in pulse-generating devices. However, in practical applications, the discharge loop of the Marx often includes stray capacitance and inductance, which can cause oscillations at the leading edge of the pulse.

Active Suppression of Torsional Oscillations
IFAC Proceedings Volumes, 2004Abstract A problem with electrically driven vehicles is resonances in the drive train caused by elasticity and gear play. Disadvantageous effects caused by this are noticeable vibrations and high mechanical stresses due to torque oscillations. The oscillations can be damped using a control structure consisting of a nonlinear observer to estimate the ...
