关于多项式鲁棒稳定性的几个新结果

本文基于儒歇定理，给出了系数多线性地依赖于不确定参数的多项式鲁棒稳定性的充分条件。这些判据具有简单的形式，十分容易检验。在某些特殊情况下，这些条件甚至还是必要的。本文的结论为具有不确定系数的多项式的鲁棒稳定性提供了一些新的有效的判据。

Some New Results of Robust Stability of Polynomals

Based on Rouche's theorem,his paper presents some sufficent condi-tions for the robust stability of a special kind of polynomial with multilinear parameterdependence. These criterions have simple forms and are very easy to apply. In somespecial stuations,these conditions are even necessary. The results of this paper affordus some effective new criterions for the robust stability of polynomals with uncertain co-efficients.
