An improved one-step amplitude–frequency relation for nonlinear oscillators
This paper proposes an amplitude–frequency relation which improves He’s simple, one-step, approach for approximating the frequency in the case of the cubic–quintic Duffing oscillator; the relation we apply is a weighted average amplitude–frequency relation.
