ABSTRACT
In this paper, a novel 4D chaotic system is proposed. First, the basic dynamic characteristics of this system are analyzed theoretically. Second, dynamical properties of the system are investigated by phase portraits, Poincaré sections, Lyapunov exponent spectrum and bifurcation diagram. In addition, an analog circuit of the system is designed and simulated by Multisim, a circuit simulation software. The experimental results show that the circuit simulation results are consistent with the numerical simulation results. Therefore, the existence of chaotic attractor in the system is verified from the physical level.
