Problems solved by technology

[0002] At present, many chaotic systems including the generalized Lorenz system family have been proposed, which are generally two-wing attractors. Although a chaotic system with multi-wing attractors can be realized by increasing the equilibrium point of the system, it has a double-layer butterfly attraction. The construction method and circuit realization of the sub-chaotic system have not been proposed yet, which is the deficiency of the prior art
