“…Although we have only considered the case with one parameter λ, our approach can be used for an arbitrary number of parameters, and the only difficulty would be in solving inequalities with a larger number of parameters. Moreover, we use some known families of robustly stable polynomials to illustrate the algorithm, but the methods presented in [17][18][19] provide great flexibility to generate Schur and Hurwitz robustly stable polynomials in different ways, and this approach can be used with all of them. Finally, the proposed method for Hurwitz polynomials is based in the Möbius transformation relating the unit disk with the left halfplane, and this approach introduces some restrictions on the regions where the zeros are to be located, as explained in the discussion after Example 4.…”
