This paper studies the structural properties of both ÿnite poles and the inÿnite pole of linear time-invariant singular systems under output feedback. Three main problems are studied, namely, (1) the algebraic structures of both ÿnite poles and the inÿnite pole; (2) the assignability of ÿnite poles and the elimination of the inÿnite pole by output feedback;(More)
