Abstract: The problem of designing Luenberger observers with loop transfer recovery is further discussed. Using a parametric approach for design of Luenberger observers, and employing a more general loop transfer recovery condition for the Luenberger observer——state feedback systems, a method for design of Luenberger observers with loop transfer recovery is proposed. Compared with the one before, this method has a wider application scope, and possesses less conservativity. A numerical example shows the simplicity and the effectiveness of the proposed approach.

Key words: linear systems, state feedback, Luenberger observers, loop transfer recovery
