摘要
This paper studies the problem of robust H∞ control for uncertain stochastic system with time-varying delay.The time delay is assumed to be of interval type. By constructing a new stochastic Lyapunov-Krasovskii functional, It ?o's formula and introducing free weighting matrix, sufficient conditions for delay-dependent robust H∞ control is obtained.The presented formulation is in the framework of linear matrix inequality and thus can be carried out conveniently.Finally, one numerical example is given to illustrate the effectiveness of the proposed approach.
