Abstract: |
Although interval systems have received a great deal of attention, so far there is few work on neutral stochastic interval systems (NSIS). The purpose of this paper is to initiate the study of NSIS. Using Raumikhin-type technique, a sufficient condition of exponential stability on NSIS is given. It is interesting that the NSIS changes into general stochastic interval system when the neutral item disappeared. So the results in this paper generalize some conclusions existed. |
