报告摘要:

Because a wideband noise is easily realized in applications and because it well approximates a white noise, this work focuses on delay differential equations subject to wideband noise perturbations. By using perturbed test function methods combined with martingale techniques, this paper shows that when the small parameter tends to zero, the underlying process converges to a limit that is governed by solutions of a stochastic delay differential equation. It is noticeable that this limit stochastic differential equation not only depends on the delay term, but also the second delay. Not only are the results interesting from a mathematical point of view, but also they will be of great utility to a wide range of problems in control and optimization problems.
