多输入多输出系统在凸多面体摄动模式下H_∞鲁棒性能

Robust H_∞ Performance of MIMO Systems under Polytopic Perturbation Modes

研究了多输入多输出混合摄动系统的加权H∞ 范数的检验问题 ,对象族的分子为多仿射凸多面体多项式族 ,当分母为乘积形式的多仿射凸多面体多项式族时 ,给出了棱边检验结果 ,当对象族的分母多项式族为区间多项式族或菱形多项式族时 。

The problems of weighted H ∞ norm checking for MIMO system with mixed perturbation are studied.Under the assumptions that the numerator of the transfer function of the system is a multi affine convex polytopic polynomial family and that the denominator of the plant is a multiplication of affine polytopic polynomial families,the edge checking result is obtained. And when the denominator of the plant is an interval or a diamond polynomial family,the vertex checking result is presented.
