Abstract

The present invention relates to a magnetic control memristor type Lv system hyperchaotic hidden attractor generation circuit and a construction method thereof. The hyperchaotic hidden attractor generation circuit includes an oscillation system and an equivalent realization circuit corresponding to a magnetic control memristor; and the oscillation system is connected with the equivalent realization circuit so as to present a corresponding hidden oscillation phenomenon. According to the magnetic control memristor type Lv system hyperchaotic hidden attractor generation circuit and the construction method thereof of the invention, a magnetic control memristor term, namely, a first integral channel, is added into the first equation of an original Lv system; a linear feedback term and external excitation, namely a second integral channel, is added into the second equation of the original Lv system; and a third second integral channel is kept constant; and therefore, the hyperchaotic hidden attractor generation circuit can be generated.

Description

technical field [0001] The invention relates to a memristor hyperchaotic system containing a hidden attractor, adding a magnetron memristor item to the first equation of the original Lü system, and adding a linear feedback item and an external excitation item to the second equation. A hyperchaotic hidden attractor generating circuit for magnetron-controlled memristive Lü-like systems is realized. Background technique [0002] In 1971, a new two-terminal circuit element - memristor was proposed, and the existence of the relationship between memristive charge and magnetic flux was predicted theoretically. In 2008, researchers from Hewlett-Packard in the United States realized the first circuit of memristive components. In 2009, Seagate researchers again invented a spin memristive system based on electron magnetism. In recent years, due to its nonlinearity and memory, memristive elements have broad application prospects in the research of artificial neural networks, secure co...
