RESUMO

The objective of this work is to determine when all of zeros of a given polynomial have negative real parts, called stable or Hurwitz polynomials. We will present and prove the Routh-Hurwitz criterion. Furthermore we will extend the result for classes of polynomials defined by letting their coeficients vary independently in an arbitrary finite interval. Then we will apply them to derive a robust stability condition for a mechanical system.
