Circuit realization of the fractional-order unified chaotic system

摘要

This paper studies the chaotic behaviours of the fractional-order unified chaotic system.Based on the approximation method in frequency domain,it proposes an electronic circuit model of tree shape to realize the fractional-order operator.According to the tree shape model,an electronic circuit is designed to realize the 2.7-order unified chaotic system.Numerical simulations and circuit experiments have verified the existence of chaos in the fraction-order unified system.
