報(bào)告題目：Noise-induced Dynamics in the Multi-stable Systems
內(nèi)容簡(jiǎn)介：Multi-stable dynamical systems mean the coexistence of several possible attractors for a given set of parameters. The coexistence of different stable states offers a great flexibility in the system performance without major parameter changes. Therefore, the research of noise-induced dynamics in the multi-stable systems is important because the phenomenon of multi-stability exists in many fields, such as biological systems, energy harvesting system, optical systems and social systems. In this report, the theoretical analysis and numerical simulations of the multi-stable dynamical systems driven by different noises and periodic signal are presented. The noise-induced dynamics, such as stochastic resonance, coherence resonance, noise-enhanced stability and stochastic bifurcations, are explored by considering the effects of structural parameters, time delay and noises. The proposed method and obtained results are applied to the studies of vibrational energy harvesting and fault diagnosis.
