ESA in high‐order linear systems via output feedback

This paper considers eigenstructure assignment in high-order linear systems via output feedback. Parametric expressions for the left and right closed-loop eigenvectors associated with the finite closed-loop eigenvalues and two simple and complete parametric solutions for the feedback gain matrices are obtained on the basis of the parametric solutions of the generalized high-order Sylvester matrix equations. This approach does not impose any restrictions on the closed-loop eigenvalues. An illustrative example shows the effect of the proposed approach.
