2nd Edition, as published by Charles François 2004 Presented by the Bertalanffy Center for the Study of Systems Science Vienna for public access.

About

The International Encyclopedia of Systems and Cybernetics was first edited and published by the system scientist Charles François in 1997. The online version that is provided here was based on the 2nd edition in 2004. It was uploaded and gifted to the center by ASC president Michael Lissack in 2019; the BCSSS purchased the rights for the re-publication of this volume in 200?. In 2018, the original editor expressed his wish to pass on the stewardship over the maintenance and further development of the encyclopedia to the Bertalanffy Center. In the future, the BCSSS seeks to further develop the encyclopedia by open collaboration within the systems sciences. Until the center has found and been able to implement an adequate technical solution for this, the static website is made accessible for the benefit of public scholarship and education.

OSCILLATION (Self-) 2)

← Back

An oscillation that appears spontaneously in a system.

This curious phenomenon has been first researched by POINCARÉ. S. DINER describes as follows its characteristics:

- "amplitude and frequency independent of initial conditions;

- "emergence independent of any external periodic stimulation;

- "control, through feedback, upon the energy source, in order to compensate dissipation without influencing amplitude and frequency".

DINER defines an auto-oscillator as : "A system generating non-damped oscillations, sustained by an external energy source, in a nonlinear dissipative way, and whose aspect and properties are determined by the system itself, without dependence from its initial conditions. In such conditions, oscillations can be not merely periodic, but also quasi-periodic and even stochastic. ANDRONOV (in 1929)… showed for the first time the physical existence of an attractor that was not an equilibrium point. Later the concept of attractor was to be amplified up to the emergence of the strange attractor concept, the mathematical form of stochastic self-oscillations" (1992, p.340-1).

This could be considered a kind of thermodynamic autopoiesis!
