Abstract

In this paper, a newfashioned Lorentz chaotic system are found. According to the circuit structure, we set up the dimensionless model of the circuit. In the simulation, three different shapes of chaotic attractors are found. The equilibrium point and stability of chaotic system are analyzed by using the traditional dynamical analysis methods, and the dynamical behaviors with two varying parameters of this circuit are analyzed in detail. In addition, The specific phenomenon of chaotic attractor coexistence is discovered. Finally, the circuit simulation is carried out using Multisim, and the results are compared with the numerical simulation, which proves the validity of the theoretical analysis. Combined with Theoretical analysis and simulation consequence, it is shown that the new chaotic system has abundant dynamic characteristics.
