Single-Parameter Characterizations of Schur Stability Property
Takehiro Mori, Hideki Kokame · Institutional Repositories DataBase (IRDB) · 2001
New equivalent characterizations are derived for Schur stability property of real polynomials. They involve a single scalar parameter, which can be regarded as a freedom incorporated in the given polynomials so long as the stability is concerned. Possible applications of the expressions are suggested to the latest results for stability robustness analysis in parameter space. Further, an extension of the characterizations is made to the matrix case, yielding one-parameter expressions of Schur matrices.
