Abstract
In this paper, a nonlinear coupling of two Chua circuits is presented. This circuit has been studied extensively because it has the advantage of being very simple, presenting a complex dynamics that presents chaos. That is, this behavior is presented when the Chua circuit is coupled or uncoupled.In addition to being a circuit with potential in various areas such as telecommunications. The coupled system behavior analysis allows phenomena such as information exchange and synchronization using such circuits.For dynamic analysis and stability we use classical tools of dynamic systems theory, such as Lyapunov exponent and the bifurcation diagram. We also use statistical methods of analysis of fractional systems in the integer derivative system of chua. This analysis was performed with a chaotic system and a periodic state system, so the intensity of linear and nonlinear coupling was studied by this tooling. As a result all analysis tools converged to a dynamic state of resonants, meaning we could establish the regions where coupling results in completely chaotic or periodic systems
