This paper addresses the robust strict positive realness (RSPR) problem when the uncertain polynomial family is defined by an l∞ ball in coefficient space. A new characterization of the filters solving such problem is proposed. This characterization is exploited numerically to devise polynomial filters with guaranteed l∞ robustness margin.
