Robust stability of uncertain two-dimensional (2-D) polynomial family, including polytopes of 2-D polynomials, interval 2-D polynomial family, diamonds of 2-D polynomial family, depends on that of the edge polynomials of the families.

• 不确定二维多项式族；包括多胞形二维多项式族；区间二维多项式族；钻石形二维多项式族；其鲁棒稳定性可由其棱边多项式的稳定性确定.
