Abstract :
In this paper, the variable structure control problem for a class of uncertain stochastic systems with time-varying delay is investigated. A new concept of the subordinated reachable property of the sliding motion is introduced. The variable structure control law is then proposed to ensure that the sliding motion is subordinated reachable. And a sufficient condition for mean square asymptotical stability of the sliding motion is given. A numerical example is presented to demonstrate the effectiveness of the obtained results.
