线性周期时变系统一致指数稳定性的一个注记

A note on uniform exponential stability of linear periodic time-varying systems

Robert Vrabel

摘要:

本文导出了线性周期时变系统一致稳定性的新判据$\dot x=A(t)x,$ $A(t+T)=A(t).$作为推论,建立了Floquet特征指数的上下界上界。该方法是基于使用对数范数的系统矩阵$A(t).$最后,我们分析了鲁棒性的稳定性的外部干扰。

英文摘要:

In this paper we derive new criterion for uniform stability assessment of the linear periodic time-varying systems $\dot x=A(t)x,$ $A(t+T)=A(t).$ As a corollary, the lower and upper bounds for the Floquet characteristic exponents are established. The approach is based on the use of logarithmic norm of the system matrix $A(t).$ Finally we analyze the robustness of the stability property under external disturbance.
