| Abstract: | Properties of the inverse (A − pBC)−1 are used to characterise the parameters of the infinite zeros of the root-locus of an invertible, multivariable feedback system S(A, B, C) as the solutions of constrained eigenvalue problems and to generate generic subspace conditions that guarantee only integer order infinite zeros in terms of the subspaces in the {A, B}-invariant subspace algorithm. |
