CHUA'S CIRCUIT WITH A DISCONTINUOUS NONLINEARITY

Journal of Circuits, Systems and Computers, 1993
A discrete map can be obtained from Chua's circuit1 with a discontinuous nonlinearity. Chaotic behavior is observed in the simulation of Chua's circuit with a discontinuous piecewise-linear element. The Poincaré map can be used to study the stability behavior and opens the possibility for analyzing the chaotic behavior by determining the existence of ...

Chua's Circuit: Control and Synchronization

International Journal of Bifurcation and Chaos, 2015
Chaos-based data encryption is one of the most reliable methods used in secure communications. This implies a good control of a chaotic system and a good synchronization between the involved systems. Here, experimental results are shown on the control and synchronization of Chua's circuits.

A CMOS MONOLITHIC CHUA'S CIRCUIT

Journal of Circuits, Systems and Computers, 1993
This paper presents the schematics and layout for a 2.4 µm CMOS prototype of the Chua's circuit. Our design uses VCCSs, realized using the quasilinear region of the transfer characteristics of a differential pair. The global, nonlinear characteristics of this building block are exploited to realize the Chua's diode.

CHAOS SYNCHRONIZATION IN CHUA'S CIRCUIT

Journal of Circuits, Systems and Computers, 1993
A number of recent papers have investigated the feasibility of synchronizing chaotic systems. Experimentally one of the easiest systems to control and synchronize is the electronic circuit. This paper examines synchronization in Chua's Circuit, proven to be the simplest electronic circuit to exhibit chaotic behavior.

ON THE GENERALITY OF THE UNFOLDED CHUA'S CIRCUIT

International Journal of Bifurcation and Chaos, 1996
In this paper, we study the generality of Chua's oscillator by deriving a class of vector fields that Chua's oscillator is equivalent to. For the class of vector fields with a scalar nonlinearity, we prove that under certain conditions, two such vector fields are topologically conjugate if the Jacobian matrices at each point have the same eigenvalues ...

MODELLING AND SIMULATION OF CHUA'S CIRCUIT

Journal of Circuits, Systems and Computers, 1993
Experiments with modelling and simulation of Chua's circuit are presented in order to transfer a simple explanation of its behaviour from the wonderful fairy-tale world of mathematicians to the marvellous physical world of electronic engineers. It is demonstrated that the behaviour of the circuit is based on the interaction (superposition) of two ...

DYNAMICS OF THE NONAUTONOMOUS CHUA'S CIRCUIT

International Journal of Bifurcation and Chaos, 1995
In this paper, we investigate via physical experiments and computer simulations the response of Chua's circuit under periodic external forcing. The amplitude and frequency of the external forcing form two additional control parameters, and we present bifurcation diagrams on the plane of these two parameters.

SET STABILIZATION OF A MODIFIED CHUA'S CIRCUIT

International Journal of Bifurcation and Chaos, 2005
In this paper, we develop a simple linear feedback controller, which employs only one of the states of the system, to stabilize the modified Chua's circuit to an invariant set which consists of its nontrivial equilibria. Moreover, we show for the first time that the closed loop modified Chua's circuit satisfies set stability which can be considered as

CONTROL OF n-SCROLL CHUA'S CIRCUIT

International Journal of Bifurcation and Chaos, 2009
This paper addresses the control of unstable fixed points and unstable periodic orbits of the n-scroll Chua's circuit. In a first step, we give necessary and sufficient conditions for exponential stabilization of unstable fixed points by the proposed predictive control method.
