Identification/Observation Using an Extended Luenberger Observer

This paper introduces a theory of parameter identification using an extended Luenberger observer. State augmentation is used to represent the unknown parameters, and an extended observer/ identifier is utilized to provide both state reconstruction and parameter identification. Conditions for convergence are established, and conditions are defined for the observability of the augmented system.
