The Structured Controllability Radii of Higher
Order Descriptor Systems
|
|
Nguyen Khoa Son and
Do Duc Thuan

|
Abstract. In this paper we formulate some formulas for
computing the controllability radii for higher order descriptor systems
under the assumption that the systems matrices are subjected to structure
perturbations. The proofs are based on the multi-valued generalization of
the classical Eckart-Young theorem which indentifies the distance to
singularity of a non-singular square matrix.
