Robust Absolute Stability Using Polynomial Positivity and Sign Decomposition

Parametric Robust Stability

“…When robust positivity is analyzed in a very simple function, Bernstein polynomials have advantages over sign decomposition, but when the function is not simple, sign decomposition has advantages over Bernstein polynomials (Graziano et al, 2004). There are several works using sign decomposition instead of Bernstein polynomials, some of them are: Guerrero, 2006;Keel et al, 2008; …”
