Hyperchaotic System with Unstable Oscillators.
K. Murali, A. Tamaševicius, G. Mykolaitis, Namajunas, and E. Lindberg

A simple electronic system exhibiting hyperchaotic behaviour is described. The system includes two nonlinearly coupled 2nd order unstable oscillators, each composed of an LC resonance loop and an amplifier. The system is investigated by means of numerical integration of appropriate differential equations, PSPICE simulations and hardware experiments. The Lyapunov exponents are presented to confirm hyperchaotic mode of the oscillations.
Key words: hyperchaotic behaviour, coupled unstable oscillators, Lyapunov exponents.
