Fundamental theorem of proportional state feedback for descriptor systems

Petr Zagalak and Vladimír Kučera


The limits of proportional state feedback are studied in altering the dynamics of linear descriptor systems. A necessary and sufficient condition is given for a list of polynomials and integers to represent the finite and infinite pole structure of a system obtained by proportional state feedback from the given system.
