Eigenvalue-eigenvector sensitivity analysis of linear time-invariant singular systems

This note refers to the eigenvalue-eigenvector sensitivity analysis of linear time-invariant multivariable singular systems. Procedures that can be easily programmed on a digital computer are presented for the determination of the deviation of the eigenvalues and the corresponding right and left eigenvectors which are caused by the system´s parameter changes about their nominal values. The method is illustrated by two examples.
