摘　　要：针对实际控制系统中 ,特别是采用 Microsoft Windows平台的计算机控制系统 ,普遍存在采样周期不稳定问题 ,详细讨论了该问题中系统采样周期扰动的鲁棒边界 .基于几条对于离散系统非常普遍的假设 ,经过理论推导 ,得到了一个仅与理想系统参数 A0 及 T0 有关的采样周期扰动τ的鲁棒边界 .这一鲁棒边界的确定 。The robust bound to linear discrete systems is expounded owing to the disturbances of sampling periods, which is generally in practical digital control system, especial in which are with the Microsoft Windows as the operation system.It is obtained that robust bound τ is only related on the A 0 and T 0, which are the parameters of the ideal system, based on some general assumptions on the diserete systems.The conclusion of this article makes a theoretic foundation for the design of control systems.
