ON STABILITY DEFINITIONS OF DYNAMICAL SYSTEMS [PDF]

open access: greenProceedings of the National Academy of Sciences, 1965
Introduction.—The dominant subject in the analysis of dynamical systems is the stability of the insuing motion. Many fields of interest under current research involve dynamical systems. These range from fields such as astrodynamics, meteorology, and control systems to biology, chemistry, medicine, and economics.

Stability concepts of dynamical systems

open access: bronzeInformation and Control, 1966
Many fields of interest under current research involve dynamical systems. In these fields dynamical systems can be formulated, and their stability examined as a special case of problems of stability in dynamics.

Control of dynamic biped walking machine with limited friction in foot [PDF]

open access: yesНаучно-технический вестник Брянского государственного университета, 2023
A non-trivial problem in the biped walking is the preservation of stability under external influences without slowing down velocity. A dynamic walking control algorithm with a hierarchical structure is proposed in the article.

On stability of the Darwinian dynamics [PDF]

open access: yes, 2021
AbstractHere we analyze Darwinian dynamics of cancer introduced in [1], extended by including a competition matrix, and evaluate (i) when the eco-evolutionary equilibrium is positive and (ii) when the eco-evolutionary equilibrium is asymptotically stable.
