Abstract :
Proposes an algorithm which enables the authors to characterize positive realness and three different classes of strict positive realness in terms of Riccati equations and inherent integrations. It has been an open question whether or not the feedback system consisting of a weakly strict positive realness and a nonlinear passivity is asymptotically stable. The paper also shows that the statement is indeed the case
