TORUS-DOUBLING BIFURCATIONS IN 4 MUTUALLY COUPLED CHUA CIRCUITS

Coupled oscillators are complicated high-dimensional dynamical systems . They can exhibit a wide variety of rich dynamics which could lead to novel applications in engineering. In this brief we describe a loots- doubling phenomenon observed from four mutually coupled Chua's circuit s. The qualitative dynamical behavior of the coupled system is robust, yet the exact behavior is very sensitive to the initial conditions an d the parameter values of the Chua's circuits. We present numerical si mulation results from the system model which are in good qualitative a greement with the experimental measurements.
