Abstract :
This paper studies the Hurwitz stability of interval polynomials which can drop in degree from a Nyquist point of view. These families make it possible to deal with system families taking into account different dynamic behaviors in the modeling of a plant. The behavior of the interval polynomials is studied, and it is proven that Kharitonov´s theorem can be extended
