Wigner chaos and the fourth moment [PDF]

, 2012
We prove that a normalized sequence of multiple Wigner integrals (in a fixed order of free Wigner chaos) converges in law to the standard semicircular distribution if and only if the corresponding sequence of fourth moments converges to 2, the fourth ...

Controlling chaos in area-preserving maps [PDF]

, 2004
We describe a method of control of chaos that occurs in area-preserving maps. This method is based on small modifications of the original map by addition of a small control term.

Chaos Control in Mechanical Systems

Shock and Vibration, 2006
Chaos has an intrinsically richness related to its structure and, because of that, there are benefits for a natural system of adopting chaotic regimes with their wide range of potential behaviors.

Optimal Sliding Mode Chaos Control of Direct-Drive Wave Power Converter

IEEE Access, 2019
In this paper, in order to investigate the chaos control problem of direct-drive wave power conversion system, the hydrodynamic model of Archimedes wave swing and the state equation of permanent magnet linear synchronous motor are analyzed, and a ...

Controlling chaos in a chaotic neural network [PDF]

, 2003
The chaotic neural network constructed with chaotic neuron shows the associative memory function, but its memory searching process cannot be stabilized in a stored state because of the chaotic motion of the network.
