摘要: Periodic solutions occur commonly in linear or nonlinear dynamical systems. In some cases, the stability of a periodic solution holds if rightmost characteristic root has negative real part. Based on Lambert W function, this paper presents simple algorithm for locating oscillators with large time delay. As application, proposed is used to study primary resonance and 1/3 subharmonic Duffing oscillator under harmonic excitation delayed feedback, as well control problem van der Pol by using number case studies. The main advantage that though very implementation, it works effectively high accuracy even delay large.
