Numerical computation of decentralized fixed modes
In this paper, we use an algebraic characterization of "fixed modes" of a decentralized linear multivariable system to show that the fixed modes are related to the "blocking zeros" of certain subsystems derived from the given decentralized system. A numerical algorithm is then presented which enables us to compute the fixed modes in a reliable manner. Examples are provided to illustrate the main results of the paper. © 1991.
