External Feedback Research On Stochastic Resonance And Its Numerical Simulation Control

This paper mainly studies the influence of external feedback control of stochastic resonance. By adding feedback control factors, adjusted stochastic resonance. This paper studies the influence of different factors on the control of stochastic resonance problems.This paper studies the concrete control method of two kinds of stochastic reso-nance is different, the linear feedback control method and the nonlinear feedback con-trol method.Numerical simulation results show that the influence factors of two differ-ent control methods of stochastic resonance is different.The linear feedback control of stochastic resonance in the strength increase with the increase of the intensity of the control, nonlinear feedback control, stochastic resonance intensity weakened with in-creasing control strength.At the same time, the emergence of cusp metastable state in the potential function in the linear feedback control.
