Dynamic properties research for an autonomous chaotic system

In this paper, a new chaotic system is constructed. This system contains four parameters and two nonlinear terms. The fractal dimension and the stability of equilibrium point are analyzed in the system. The impact of the system parameters is given by analyzing the bifurcation diagram and Lyapunov exponent. Meanwhile, the circuit of the chaotic system is designed by using Mutisim software. The conclusion confirms the consistency of the numerical simulation and circuit. It reveals that this system has abundant dynamics characteristic and the realization of chaotic systems.
