线性系统稳定鲁棒界研究

On Perturbation Bound for Robust Stability in Linear Systems

研究渐近稳定的线性时不变系统在受到连续扰动时,受扰系统保持稳定的问题.通过采用该系统极点位于S 左米开平面这一系统稳定的充要条件,得以了使系统保持稳定的最大结构生摄动界。算例证明了这一结果优于许多已发表的其它结果。

A symptotically stable linear timeinvariant systems under continuousperturbation are considered to maintain stability in this paper.Utilizing the necessaryand sufficient condition for systems stability,or keeping systems poles in the left openS—plene,Upper structural perturbation bound for systems stability is obtained.Themerits of our developed result are demonstrated by an example.
