Description

technical field [0001] The invention belongs to the field of information encryption, in particular to an integer-order nonlinear chaotic system circuit. Background technique [0002] Nonlinear science has been called the "third revolution" in the scientific world. Nonlinear science is closely related to all areas of people's lives, and has gradually changed people's world outlook. It makes people's thinking more active, and their consideration of problems is more comprehensive and rational. Scholars generally believe that nonlinearity is mainly composed of three parts, which are chaos, fractals and solitons. Therefore, chaos theory plays an important role in nonlinear disciplines. The study of chaotic systems has great potential value for the progress of science and technology. [0003] Chaos is a deterministic behavior exhibited by a definite nonlinear dynamical system, and it is a manifestation of irregular motion in a regular system. In 1963, Professor Lorenz discovere...

Problems solved by technology

However, there are still some differences between the numerical simulation and the actual circuit structure, especially due to the limitation of the physical characteristics of the actual components, the theoretically derived chaotic circuit may not be successfully reproduced in the actual circuit.
