Abstract
In this paper, we first establish the existence and uniqueness theorem for solutions of Caputo type fractional stochastic delay differential systems by using delayed perturbation of Mittag-Leffler function. Secondly, we obtain an averaging principle for the solution of the considered system under some suitable assumptions. Finally, two simulation examples are given to verify the theoretical results.
