A novel multi-directional multi-scroll chaotic system and its CCII+ circuit implementation

This paper proposes a generalized formula of multi-directional multi-scroll chaotic system. Based on the generalized formula, by adding the nonlinear functions, and controlling the parameters of system, multi-directional multi-scroll chaotic attractors with different order system can be generated. According to this method, the correctness of generalized formula is verified. Then, basic dynamic characteristics of the system including the fractal, equilibrium points, Poincare section, Lyapunov exponent spectrum and bifurcation diagram are analyzed. Finally, a nine-dimensional chaotic circuit based on CCII+ devices is designed, which verified the feasibility of the generalized formula and multi-directional multi-scroll chaotic circuit with CCII+ devices.
