Abstract :
A parametric approach, based on a canonical form of the singular matrix pencils and a result about the regularizability of linear descriptor systems, is proposed for infinite eigenvalue assignment (IEVA) in linear, continuous and time-invariant descriptor systems via proportional plus derivative state feedback. When the input and state vectors have the same dimension, it is proved that there are solutions to the IEVA problem. A representation of all these solutions is given. When the input and state vectors have different dimensions, necessary and sufficient conditions under which the IEVA problem has at least a solution are presented and a parametric expression of a class of all solutions is given. A design algorithm and two test examples show the efficiency of the proposed approach.
