[0038] figure 1 Shown is the design flowchart of the present invention. Based on the three-dimensional Lorenz chaotic system, anti-disturbance control is applied to construct a four-dimensional dynamical system. Verify whether the four-dimensional dynamical system meets the three necessary conditions of the hyperchaotic system (the three-dimensional Lorenz chaotic system under the action of anti-disturbance control must meet the three neces...

Abstract

The invention discloses a disturbance rejection control design method for constructing a hyperchaotic system and a hyperchaotic circuit. The hyperchaotic circuit comprises four channel circuits. The output signal x of the first channel circuit is used as an input signal of the second, third and fourth channel circuits, and is simultaneously used as an input signal of the first channel circuit and the second channel circuit after being inverted by an inverter. The output signal y of the second channel circuit is used as an input signal of the first, third and fourth channel circuits. The output z of the third channel circuit is used as an input signal of the second channel circuit and the fourth channel circuit. The output u of the fourth channel circuit is used as an input of the first channel circuit. The hyperchaotic circuit can obtain hyperchaotic dynamic characteristics within a large parameter range.

Description

technical field [0001] The invention relates to a method for constructing an ultra-chaotic system on the basis of a chaotic system, specifically a systematic design method for constructing an ultra-chaotic system by using the chaotic system. Background technique [0002] Chaos is a kind of random-like dynamic behavior generated in deterministic systems. Because of its rich dynamic behavior, it is widely used in the field of secure communication. Compared with ordinary chaotic systems, hyperchaotic systems have more than one positive Lyapunov exponent, and their dynamic behavior is more complex and difficult to predict than ordinary chaotic systems. Therefore, in secure communication, hyperchaotic systems have greater advantages. In addition, the hyperchaotic system has extremely advantageous application prospects in information encryption, image processing, complex networks, and nonlinear circuits. [0003] Just because hyperchaotic systems have broad application prospect...
