摘要 利用灰矩阵的矩阵覆盖集的分解技术和矩阵的范数理论及Lyapunov-K rasovsk ii泛函法,研究了具有分布时滞的灰色随机非线性系统的鲁棒稳定性问题,得到了该系统鲁棒稳定的时滞依赖的线性矩阵不等式(LM Is)判据,并通过数值例子说明了所得的"LM Is判据"的有效性和实用性. The robust stability of grey stochastic nonlinear systems with distributed-delays is investigated by using the decomposition technique of the matrix-covered set of grey matrix and theory of matrix norm and by constructing Lyapunov-Krasovskii functional. The delaydependent Criteria for robust stability are obtained in term of linear matrix inequalities. A numerical example shows the effectiveness and practicality of the presented LMIs Criteria.
