Partial eigenvalue assignment problem of linear control systems using orthogonality relations [PDF]

open access: yesActa Montanistica Slovaca, 2006
The partial eigenvalue assignment is the problem of reassigning a part of the open-loop spectrum of a linear system by a feedback control, leaving the rest of the spectrum invariant.
