The effect of fractional damping and time-delayed feedback on the stochastic resonance of asymmetric SD oscillator

This paper proposes the stiffness nonlinearities and asymmetric SD (smooth discontinuous) oscillator under time-delayed feedback control with fractional derivative damping. With effect of displacement velocity feedback, can be adjusted to desired vibration state, then stochastic resonance (SR) is achieved. article discusses contribution various system parameters SR, especially which induced by order. It should noted that this provides effective guidance for fault diagnosis weak signal detection, energy harvesting, isolation reduction.
