Embodiment Construction

[0038] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0039] figure 1 It is a system frame diagram of a chaos control method based on an artificial neural network in the present invention. It mainly includes Lorentz oscillator, Chua's circuit, artificial neural network (ANN), using ANN to control chaos.

[0040] Among them, the use of artificial neural network (ANN) can effectively control chaos, obtain the required output from the chaotic system, and use ANN can lead to a stable chaotic system; the main problem in achieving this desired result is the time required to adjust the ANN weights, First, manually adjust Chua's output resistance one by one, and then automatically control the system by feedback.

[0041] Chaos is defined as the...

Abstract

The invention provides a chaotic control method based on an artificial neural network. A Lorentz oscillator, a Chua circuit and the artificial neural network (ANN) are mainly included. The ANN is used to control chaos. A process is characterized in that the Chua circuit is constructed on a panel; output displayed on an oscilloscope is tested and acquired; a simulation analysis program is used to redraw an electronic circuit of each component of the ANN; output of an ANN circuit is connected to the Chua circuit, and one part of circuit output is fed back to the ANN; a weight is correspondingly adjusted; and through learning, the ANN adjusts a parameter of the Chua circuit and gives out required output. In the invention, the ANN is used to effectively control a chaotic system, the required output is acquired from the chaotic system, control stability is provided and automation is realized; the chaotic system is controlled so that functions in other applications can be realized.

Description

technical field [0001] The invention relates to the field of chaos control, in particular to a chaos control method based on an artificial neural network. Background technique [0002] In recent years, scientists and scholars have shifted from the observation and research of chaotic phenomena to looking for the interrelationship and internal connection of chaotic behavior among various disciplines, so as to seek common laws and systematic methods that a large class of complex problems generally follow. Because of its great research value and promising application prospect in engineering technology, chaos control has become a new research field of nonlinear science application. Chaotic system control has many potential applications, such as heat transfer, biological systems, laser physics, chemical reactors, biomedicine, economics, weather and security communications, and even shows increasing importance in scientific research and national defense. status. However, today's ...
