一类Schur区间多项式

A Class of Schur Interval Polynomials

在实参数空间中，利用多项式根界估计方法来研究结构型摄动离散系统的鲁棒稳定性问题，即Ｓｃｈｕｒ稳定性问题．得到了一类区间多项式Ｓｃｈｕｒ稳定的充分性条件．

n the real parameter space,the problems of the robust Stability of discrete sysems with the structured perturbations are developed by using the evalution methods of root bounds,i.e.,the problems of Schur stability.The sufficient conditions of Schur stability are obtained for a class of interval polynomials.
