The hallmark of deterministic chaos, an extreme sensitivity to initial conditions, suggests that chaotic systems might be difficult if not impossible to control, since any perturbations used for control would grow exponentially in time. Indeed, this quite reasonable view was widely held until only a few years ago. Surprisingly, the basis for controlling chaos is provided by just this property, which allows carefully chosen, tiny perturbations to be used for stabilizing virtually any of the…

Chaos control in mechanical systems

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.

CONTROLLING CHAOS IN A NONLINEAR PENDULUM

Chaotic behavior of dynamical systems offers a rich variety of orbits, which may be controlled by small perturbations in either a specific parameter of the system or a dynamical variable. Therefore,

Reliability of unstable periodic orbit based control strategies in biological systems.

Results suggest that establishing determinism from unambiguous UPO detection is often possible in short data sets with significant noise, but derived dynamical properties are rarely accurate and adequate for controlling the dynamics around these UPOs.

A New Method For Synchronization Of A Simple Chaotic systems

A new algorithm for controlling a class of simple chaotic system that contain only one nonlinear term that depends only on the nonlinear coupling term which makes the largest conditional Lyapunov exponents of the response system negative.

Numerical and experimental investigation of the effect of filtering on chaotic symbolic dynamics.

It is found, through numerical computations and experiments with a chaotic electronic circuit, that with reasonable care the computed or measured entropy values can be preserved for a wide range of the filtering parameter.

Feedback Synchronization using pole-Placement Control

It is shown how two chaotic systems can be synchronized by applying small feedback perturbations to one of them by describing a feedback approach for synchronizing chaotic systems that is applicable in high dimensions.

This chapter discusses controlling chaos using time delay coordinates, a new method of controlling a chaotic dynamical system by stabilizing one of the many unstable periodic orbits embedded in a chaotic attractor through only small time dependent perturbations in some accessible system parameter.

Synchronization in chaotic systems.

This chapter describes the linking of two chaotic systems with a common signal or signals and highlights that when the signs of the Lyapunov exponents for the subsystems are all negative the systems are synchronized.

DETERMINISTIC chaos is characterized by long-term unpredictability arising from an extreme sensitivity to initial conditions. Such behaviour may be undesirable, particularly for processes dependent
