Description

technical field [0001] The invention relates to a chaos generation system and circuit, in particular to a 4×2 grid multi-scroll chaos attractor system and circuit. Background technique [0002] In the early 1990s, based on the normalized state equation of the Chua circuit, Suykens and Vandewalle discovered multi-scroll chaotic attractors by increasing the turning point of the nonlinear function curve. Low-dimensional chaotic systems can be deciphered by conventional deciphering methods such as phase space reconstruction, regression mapping, and nonlinear prediction, while high-dimensional multi-scroll chaotic systems with complex behaviors are still difficult to decipher. Compared with the traditional single-scroll and double-scroll chaotic systems, the multi-scroll chaotic system has phase-orbit separation in more directions and has more complex nonlinear dynamic behavior, which can resist conventional deciphering methods and improve chaotic secure communication. The secur...
