Reduced order dead-beat observers for the chemostat

Iasson Karafyllis, Zhong Ping Jiang

Research output: Contribution to journalArticlepeer-review


This paper studies the strong observability property and the reduced-order dead-beat observer design problem for a continuous bioreactor. New relationships between coexistence and strong observability, and checkable sufficient conditions for strong observability, are established for a chemostat with two competing microbial species. Furthermore, the dynamic output feedback stabilization problem is solved for the case of one species.
