Abstract: We explore the problem of memory-enhanced stability occurring in a fractional oscillator with fluctuating eigenfrequency when the oscillator is driven by external sinusoidal forcing and by an additive internal fractional noise with a power-law type memory. It is established that at intermediate values of the memory exponent the energetic stability of the oscillator is significantly enhanced. We show that, by conveniently choosing the system parameters, the output signal-to-noise ratio is a double peaked function of the memory exponent, thus demonstrating the phenomenon of memory controlled stochastic multiresonance. The connection between the occurrence of energetic instability and the phenomenon of memory-induced multiresonance is established.
Keywords: Fractional oscillator, stochastic resonance, fractional noise, white noise, energetic instability, viscoelastic friction.
