Nonregular 2D descriptor delay systems
Stephen L. Campbell · IMA Journal of Mathematical Control and Information · 1995
This paper examines descriptor systems with delays which are in the form Bx′(t) + Dx(t) + Cx(t − α) = Eu(t) . Previous paper have examined the case when λB + D is a regular pencil. In this paper we examine the case when λ B + D is a singular pencil but det(λ B + D + ω C )≢0. Behaviour not previously reported for descriptor systems is observed. Several basic issues are discussed.
