The problem of positive asymptotically stable realizations and relations between them is addressed. Sufficient conditions for existence of the positive asymptotically stable realizations of linear continuous-time systems with real negative poles and zeros are established. A matrix of similarity transformation is proposed which preserves the positivity and asymptotic stability of the linear systems.
