Circuit realization of the fractional-order unified chaotic system

This paper studies the chaotic behaviours of the fractional-orderunified chaotic system. Based on the approximation method infrequency domain, it proposes an electronic circuit model of treeshape to realize the fractional-order operator. According to the treeshape model, an electronic circuit is designed to realize the2.7-order unified chaotic system. Numerical simulations and circuitexperiments have verified the existence of chaos in thefraction-order unified system.
