ROBUST STABILITY OF A FAMILY OF NONLINEAR STOCHASTIC DELAY SYSTEMS

In this paper we investigate exponential stability of a family of nonlinear stochastic delay systems with uncertainties.For such systems,we establish sufficient criteria for the exponential stability in mean square and the almost sure exponential stability.These criteria are dependent of delay.Furthermore,we apply these sufficient condtions to a class of stochastic delay neural networks with uncertainties and obtain practical criteria to test exponential stability of these stochastic delay neural networks.Finally, a numerical example is given to illustrate the effectiveness of the obtained criteria.
