Theory and numerics of vibrational resonance in Duffing oscillators with time-delayed feedback

摘要: The influence of linear time-delayed feedback on vibrational resonance is investigated in underdamped and overdamped Duffing oscillators with double-well single-well potentials driven by both low frequency high periodic forces. This task performed through theoretical approach numerical simulation. Theoretically determined values the amplitude force delay time at which occurs are very good agreement A major consequence that it gives rise to a or quasiperiodic pattern profile respect parameter. An appropriate shown induce an system otherwise not possible. For range parameters, response found be larger than delay-time feedback-free systems.
