رزونانس تصادفی در سیستم های برق فشار قوی تحت نوسانات همراه تحریک شده توسط نویزهای سه قسمت متقارن

In this work, we analyze the phenomenon of stochastic resonance (SR) in coupled underdamped bistable systems induced by independent symmetric trichotomous noises. Firstly, the system is found to exhibit intermittent jumping motion between two wells in an optimal range of noise values. Then, the effects of noise on the output power spectrum of the system are characterized. It demonstrates that stochastic resonance behavior can occur above a particular value of noise strength. Finally, the signal-noise-ratio (SNR) for different parameters is computed numerically. Remarkably, for different parameters, a non-monotonic behavior of SNR is shown and the impacts of trichotomous noise and Gaussian white noise on the SNR curve are researched.
