Abstract :
The notions of externally positive and internally positive time-varying linear systems are introduced. Necessary and sufficient conditions for the external positivity and internal positivity of time-varying linear systems are established. Sufficient conditions for the reachability of internally positive time-varying linear systems are presented.
