چکیده

DYNAMICS FOR WEAK COUPLING OF CHAOTIC SYSTEMS Zbigniew Galias Department of Electrical Engineering, University of Mining and Metallurgy, Krak ow, Poland [email protected] Abstract| In this paper we study behavior of coupled continuous{time chaotic systems by means of independent symbolic dynamics. First we consider the perturbed chaotic system and estimate the maximum perturbation range for which the symbolic dynamics survives. If the coupling is small enough then the perturbation introduced by the coupling does not exceed the maximumrange and there exists independent symbolic dynamics for every coupled subsystem. As an example we consider coupled Chua circuits. We compute the value of the coupling strength for which the symbolic dynamics in every subsystem is not destroyed.

Chaotic dynamics and synchronization of fractional order PMSM ‎system

‎In this paper, we investigate the chaotic behaviors of the fractional-order permanent magnet synchronous motor (PMSM) system. The necessary condition for the existence of chaos in the fractional-order PMSM system is deduced and an active controller is developed based on the stability theory for fractional systems. The presented control scheme  is simple and flexible, and it is suitable both fo...

Robustness of symbolic dynamics

In this paper we introduce the method for investigation of coupled chaotic systems using topological methods. We show that if the coupling is small then there exists independent symbolic dynamics for every coupled subsystem and in consequence the systems are not synchronized. As an example we consider coupled H enon maps. Using computer interval arithmetic we nd parameter mismatch and perturbat...

Conservative chaotic flow generated via a pseudo-linear system

Analysis of nonlinear autonomous systems has been a popular field of study in recent decades. As an interesting nonlinear behavior, chaotic dynamics has been intensively investigated since Lorenz discovered the first physical evidence of chaos in his famous equations. Although many chaotic systems have been ever reported in the literature, a systematic and qualitative approach for chaos generat...

Frequency–driven chaos in the electrical circuit of Duffing-Holmes oscillator and its control

Accurate detection of weak periodic signals within noise and possibility of secure messaging have made Duffing oscillator (DO) highly important in the field of communication. Investigation on the properties of DO is thus ardently sought for. An elegant approach to accomplish the same is to fabricate electronic circuit simulating DO non-linear equation and to study the effect of input signal amp...

Model Based Method for Determining the Minimum Embedding Dimension from Solar Activity Chaotic Time Series

Predicting future behavior of chaotic time series system is a challenging area in the literature of nonlinear systems. The prediction's accuracy of chaotic time series is extremely dependent on the model and the learning algorithm. On the other hand the cyclic solar activity as one of the natural chaotic systems has significant effects on earth, climate, satellites and space missions. Several m...
