摘 要：In this paper,a new four-dimensional four-wing chaotic circuit based on Qi chaotic system is proposed and the nonlinear characteristics are analyzed from the point of view of symmetry,dissipation and equilibrium ***,numerical analysis methods of nonlinear circuit,such as phase diagram,bifurcation diagram and Lyapunov exponent spectrum,are used to study the rich dynamic behavior with the change of system parameters and initial *** results indicate that the nonlinear system can generate attractor with different topological under distinct system ***,the coexistence of this system is abundant with diverse initial ***,the experimental results of circuit are in agreement with the numerical simulations which prove the circuit implantation of system is feasible completely.
