摘　　要：给出了滞后时变离散系统的稳定性判据。基于Ｌｙａｐｕｎｏｖ稳定性理论，应用向量比较原理，研究了滞后时变离散区间系统的稳定性，和具有非线性时变摄动的滞后时变离散系统的鲁棒稳定性，得出了一些充分条件。所得结论包含了一些已有结果作为特例。The stability criteria for delay time-varying discrete systems are first given.Then,based on Lyapunov stability theory and applied the vector comparison theorem,stability for delay time-varying interval coefficient discrete systems is studied and robust stability for delay time-varying discrete linear systems with nonlinear time-varying perturbations is also considered.Some sufficient conditions are obtained.The new results derived in this paper include the main results in some previous paper.

关 键 词：离散系统 滞后系统 时变系统 区间参数 稳定性
