不确定系统鲁棒稳定性分析—扰动界的估计

The Analysis of Robust Stability for Uncertain Systems-Aestmation of the Disturbance bound

利用隐函数的理论 ,给出不确定系统矩阵A0 +ΔA的特征根λ在标称点A0 处的导数矩阵 ,它对于研究特征根函数λ =λ(A0 +ΔA)在标称点A0

In the paper,to make use of the implicit function theeory, a derivative matrix of the eigenvalue function λ=λ(A 0+ΔA) at the A 0 is given. It is very convenience to study the rariation for the eigenvalue near A 0.
