Exploring chaotic dynamics with absolute-embedded sinusoidal nonlinearity in a sinusoidal-enhanced Van der Pol oscillator
The present study aims to analyze the chaotic behavior of a simple electrical circuit with a nonlinear resistor and an absolute value in its sinusoidal nonlinearity function. This type of circuit is considered fundamental, because it contains both nonlinear capacitance and resistance. This study investigates into various aspects of the circuit's behavior, with a particular focus on its chaotic properties such as bifurcation, periodicity, resonance, and Lyapunov exponent analysis. It is essential to highlight that, in addition to its chaotic behavior, the system also
