研究了不确定变时滞随机系统的鲁棒均方指数稳定性问题,不确定性是范数有界的.通过构造Lyapunov泛函,得到了基于线性矩阵不等式的鲁棒均方指数稳定的充分条件.最后给出实例加以验证所提出方法的有效性.
The problem of robust mean square exponential stability for uncertain stochastic systems with time-varying delay is discussed. The uncertainty is assumed to be of norm-bounded form. The robust mean square exponential stability condition is then derived on the basis of linear matrix inequalities by constructing Lyapunov-Krasovskii functional. Finally, a numerical example is given to illustrate the effectiveness of the proposed method.
