摘要
给出了离散线性系统在时变扰动下的鲁棒稳定性判据和受扰系统保持稳定的允许扰动的界限，并将此应用于多变量反馈控制系统的鲁棒状态反馈和输出反馈的设计，从而进一步发展了离散系统鲁棒稳定性理论。
Obtains the criteria for the stability robustness of discrete linear systems in the presence of the time variant perturbations and derives through the lyapunov stability approach explicit bounds on the perturbations of a discrete linear system to maintain stability. Applies the criteria to the stability robustness analysis of multivariable feedback systems.
