Article Description

This paper investigates the occurrence of extreme events (EEs) in a Sprott-like autonomous third-order nonlinear system exhibiting non-hyperbolic nature. The presence of non-hyperbolicity in the system leads to various dynamic behaviors such as quasi-periodicity, multistability, crisis, and intermittency. In our study, we analyzed the large-amplitude intermittent chaotic oscillations using time series analysis, one-parameter bifurcation diagram, Lyapunov spectra, and two-parameter phase diagram. We confirmed the existence of EEs statistically using probability distribution functions (PDFs). To validate the numerical results, we performed circuit simulation studies using OrCAD PSpice as well as real-time experimental observations using hardware implementation of the electronic circuit. In our studies, we find that the numerical, simulation, and experimental results are in agreement with each other.
