Persistence Analysis of Discrete-Time Interconnected Positive Systems and its Application to Mobile Robot Formation
Résumé
This paper addresses the analysis of discrete-time interconnected systems where each subsystem is stable and positive. Admissibility and persistence notions are derived similar to the continuous-time case and a condition for enforcing persistence is derived for the case when all subsystems are single-input single output. Results are applied on numerical examples including the formation control of mobile robots.
