Improved Design and Numerical Calculation of Chaotic Circuit in Jerk System

Abstract

Chaotic secure communication has always been a hot topic in nonlinear circuit research. In this paper, an improved jerk chaotic circuit is designed by using cell circuits and nonlinear function circuits. Simulation results show that the circuit can generate multi-scroll chaotic attractors. The position and number of chaotic attractors can be controlled by adding or deleting the number of nonlinear function circuit or by adjusting its parameters. Theoretical analysis and numerical calculation show that the circuit can describe jerk system, and the calculation results are consistent with the circuit simulation results. The circuit is not only simple in structure, easy to operate and high in experimental accuracy, but also easy to control chaos, which is widely used in secure communication.
