Abstract

The invention relates to the technical field of non-linear dynamics, and provides a design method of a multi-scroll chaotic attractor circuit. The design method comprises the following steps: acquiring a reference state equation according to a state equation of a double-scroll Chua's circuit and a symbol function; generating a circuit state equation according to a multi-scroll Chua's circuit and a symbol function generating circuit; and acquiring device parameters in the multi-scroll Chua's circuit and the symbol function generating circuit according to the reference state equation and the circuit state equation. Through adoption of the design method, the symbol function is introduced on the basis of an existing Chua's circuit, and a novel nonlinear chaos generation multi-scroll attractor system model is constructed. A system is stable and reliable, and easy to debug. 2n scrolls can be obtained by computer simulation, and a plurality of scrolls can be obtained in an actual hardware circuit.

Description

technical field [0001] The invention relates to the technical field of nonlinear dynamics, in particular to a design method of a multi-scroll chaotic attractor circuit. Background technique [0002] At present, the field of hybrid motion has successively proposed methods to generate multiple scrolls by using sine functions, triangular wave sequences, and time-delay functions, and it is not surprising to use computers to simulate chaotic attractors with more than 10 scrolls. It is not easy to generate chaotic attractors with more than 10 scrolls in the circuit. According to the existing literature reports, the hardware experiment results of obtaining 11 scrolls in one direction by using a typical Chua circuit are the latest research results. At the same time, studies have shown that encryption using low-dimensional simple chaotic systems can already be deciphered, while high-dimensional multi-vortex with complex behavior is still difficult to decipher. In summary, it is diffi...
