Nonlinear response analysis of the Duffing-Van der Pol oscillator with external excitation using a modified Lindstedt-Poincaré method

The Van der Pol oscillator is well known for generating a self-sustained limit cycle in its unforced state; however, when an external periodic force is applied, its dynamical responses may deviate sharply away from this natural rhythm. The existing Lindstedt-Poincaré method becom...
