中文摘要:提出一个新的线性时滞系统稳定的充分必要条件,与以前的结论不同的是,我们的结论的表达形式更容易数值计算。开发相应的二种收敛算法,解决系统时滞独立稳定判断和时滞相关稳定的时滞界估计。本文给出范数有界不确定性时,系统稳定的充分条件。文末给出的数值实例证明本文结果降低计算复杂度,改进了时滞估计保守性。

A Sufficient and Necessary Stability Condition for Linear Systems with Delay
Abstract:This note provided a new sufficient and necessary stability condition for time-delay systems. Unlike previous methods, the mathematical descriptions here are easy to numeric computation. Two algorithms were developed and used to solve the problems of both time-independent and time-dependent stability. When time-varying norm-bounded uncertainties appear in a delay system, a robust delay-dependent stability condition was given. Examples were provided to demonstrate the reduced complexity and conservatism of the proposed conditions.
