Problems solved by technology

[0003] 2. American scholar Sprott proposed a large class of new third-order chaotic circuits around 2000. Its main feature is to generate chaotic attractors such as single-layer single-helix and single-layer double-helix, but its limitation is that it cannot generate three and more than three spiral chaotic attractors

Embodiment Construction

[0052] American scholar Sprott proposed a class of chaotic circuits in 2000, whose state equation can be expressed as

[0053] dx / dτ = y dy / dτ = z dz / dτ = - βz - y + f ( x ) - - - - ( 1 )

[0054] Where β=0.6, the circuit such as figure 1 shown. When f(x)=|x...

Abstract

The invention discloses a multispiral chaos generator, comprising an integrator N0, a generator N1 of three sectionally linear odd functions each with an adjustable turning point value alpha, nine symbol functions generator, a linear function generator N3 and seven switchers K1, K2, K10, K11, K12, K13 and K14; as the switcher K2 is closed and K1 opened, using N0, N2 and N3 and the switching of K10, K11, K12, K13 and K14 to be able to separately generate eight different multispiral chaos absorbers together: three-spiral, four-spiral, five-spiral, six-spiral, seven-spiral, eight-spiral, nine-spiral and ten-spiral ones; as K1 closed and K2 opened, using N0 and N1 to generate four different unispiral and double-spiral chaos absorbers: double-layer unispiral, single- layer unispiral, double-layer double-spiral and single-layer double-spiral ones.

Description

(1) Technical field [0001] The invention belongs to a chaotic circuit, in particular to a multi-spiral chaotic generator. (2) Background technology [0002] 1. How to generate various chaotic circuits required for chaotic secure communication is a new field of nonlinear circuit and system research in recent years. At present, a series of related research results have been achieved internationally, such as double scroll Chua's circuit, multi-scroll Chua's circuit, MCK super chaotic circuit, Lorentz circuit, etc. In China, Yin Yuanzhao, a researcher at the Institute of Electronics of the Chinese Academy of Sciences, invented the deformed Cai's circuit in 1998 on the basis of Cai's circuit. In addition, Zhao Geng invented the digital stream chaos generator in 2002, Zhang Hongyu invented the chaos code sequence generator in 2002, etc. [0003] 2. American scholar Sprott proposed a large class of new third-order chaotic circuits around 2000. Its main feature is to generate chao...
