Abstract
Two approaches are used to develop a 2-D algebraic stability test and to establish a link between the frequency-dependent Lyapunov equation and the frequency-dependent Routh algorithm. The 2-D algebraic test procedure consists of two steps: (1) Computing the principal minors of the frequency-dependent Bezoutian and checking if they are positive at one point; and (2) computing the last principal minors of the frequency-dependent Bezoutian. The 1-D discrete Routh algorithm is used to test the positivity of the symmetric polynomial associated with the last principal minor of the Bezoutian
