Web赫尔维茨多项式（Hurwitz polynomial)因德国数学家阿道夫赫尔维茨得名，它是一个多项式 ，其系数是正实数 ，其根部位于复平面的左半平面或虚轴上，即根的实数部分是零或负 … WebFor a monic polynomial (coefficient of z2 is unity), the constant term is equal to the product of the poles. Hence, for pole magnitudes less than unity, we obtain the necessary stability condition. This condition is also sufficient in the case of complex conjugate poles where the two poles are of equal magnitude.
