Abstract

In this paper, the sine function memristor and the cosine function memristor are connected in series, and the constructed series memristor is numerically analyzed through its volt-ampere characteristics, and then the new memristor was introduced into the Rossler system to construct a hyperchaotic system with dual memory elements. The coexistence attractor and fractal phenomena in the system are analyzed, and the fractal dimension of the system is calculated on the basis of fractal theory. In addition, analog circuits corresponding to the system are designed and simulated based on circuit theory. DSP is used for digital circuit experiments to explore the application of this system in practice.
