摘　　要：利用比较定理、矩阵范数和矩阵测度的有关性质 ,提出了简单不确定时滞系统及对称组合不确定时滞系统的稳定条件 .指出若带有时滞的系统稳定 ,则去掉时滞时系统一定稳定 .在组合系统的情况下给出了时滞相关型的稳定条件 .Using comparison theorem and some properties of the matrix norm and the matrix measure,the paper provides several stability conditions for single and symmetric composite uncertain delay systems.The results show that the systems from which the delays are removed must be sufficiently stable to ensure the stability for the systems with delays.The paper also presents the delay dependent type stability condition for the composite systems.The norm of the uncertain matrix of the systems are constrained.
