摘要:This work is concerned with the approximate controllability of nonlinear fractional impulsive stochastic differential system under the assumption that the corresponding linear system is approximately controllable. Using fractional calculus, stochastic analysis, and the technique of stochastic control theory, a new set of sufficient conditions for the approximate controllability of a fractional impulsive stochastic differential system is obtained. The results in this paper are generalizations and continuations of the recent results on this issue. An example is given to illustrate the efficiency of the main results.
