Problems solved by technology
[0002] The existing hyperchaotic system is generally based on the three-dimensional chaotic system, by adding one-dimensional variables at a time, and feeding back the added variables to the original three-dimensional chaotic system to form a four-dimensional hyperchaotic system, while the existing automatic switching chaotic system The system is generally a three-dimensional chaotic system, and the construction method and circuit of a four-dimensional hyper-chaotic system with automatic switching function have not yet been proposed, which is the deficiency of the existing technology

The invention relates to a two-system automatic switching hyper-chaos system and circuit, particularly to a Lu system based two-system automatic switching hyper-chaos system construction method and circuit. Disadvantages in the prior art comprises that, the existing four-directional hyper-chaos system is formed based on a three-dimensional chaos system through increase of a one-dimensional variable in one time and feedback of the increased variable to the original three-dimensional chaos system; the existing automatic switching chaos system is generally a three-dimensional chaos system; a construction method and circuit is not provided for the four-dimensional hyper-chaos system having an automatic switching function. According to the Lu system based two-system automatic switching hyper-chaos system construction method and circuit, a two-system automatic switching hyper-chaos system is formed based on the three-dimensional Lu system through increase of one-dimensional variables in twice and feedback of the increased variables to a second equation of the three-dimensional Lu system, a new method for constructing the two-system automatic switching hyper-chaos system is provided, the construction method is achieved through a simulation circuit, and a new selective scheme is provided for application of the two-system automatic switching hyper-chaos system into the engineering fields such as the communication field.

technical field [0001] The invention relates to a hyperchaotic switching system and an analog circuit, in particular to a construction method and an analog circuit of a 2-system automatic switching hyperchaotic system based on the Lü system. Background technique [0002] The existing hyperchaotic system is generally based on the three-dimensional chaotic system, by adding one-dimensional variables at a time, and feeding back the added variables to the original three-dimensional chaotic system to form a four-dimensional hyperchaotic system, while the existing automatic switching chaotic system The system is generally a three-dimensional chaotic system, and the construction method and circuit of the four-dimensional hyper-chaotic system with automatic switching function have not been proposed yet, which is the deficiency of the prior art. On the basis of the three-dimensional Lü chaotic system, the present invention increases the one-dimensional variable twice, and feeds back ...
