Aspects of Optimality in the Eigenvalue Assignment Problem

1989 American Control Conference, 1989
The eigenvalue assignment problem involves finding a state feedback vector k such that the eigenvalues of A-bkT are in the desired locations. This paper considers the case where the system is not completely controllable, and the solution for the feedback gain vector k is not unique.

An algorithm for Eigenvalue assignment in multi-input systems

Journal of the Franklin Institute, 1984
A method is presented for eigenvalue assignment in multi-input linear systems by means of state feedbacks. The method consists of four algorithms: Algorithm 1 reduces the given system to an upper block Hessenberg form. Algorithm 2 performs partial reduction of the state matrix of the upper block Hessenberg form by means of state feedback and orthogonal

Robust Eigenvalue Assignment by Output Feedback

IFAC Proceedings Volumes, 1997
Abstract An output periodic feedback is proposed for the robust eigenvalue assignment of linear, time-invariant, discrete-time systems. The condition numbers characterizing the eigenstructure of the closed-loop system are assumed as a robustness measure.

Eigenvalue assignment in observer and controller design

International Journal of Control, 1983
Abstract Full-order and reduced-order dead-beat observers are developed from the invariant observable canonical (IOC) form using eigenvalue assignment. Eigenvalue assignment in observer design for a general ease is then presented. Using the property of duality, the dead-beat controller is developed from the invariant controllable canonical (ICC) form ...

Eigenvalue assignment robustness for systems with structured perturbations

IEEE Transactions on Automatic Control, 1993
Summary: The eigenvalue assignment robustness problem of a linear time-invariant uncertain system is considered. Allowable perturbations are obtained for ensuring the eigenvalues of a system, with or without perturbations, be retained in some distinct and arbitrarily-shaped regions.

Eigenvalue/eigenvector assignment by state-feedback

International Journal of Control, 1977
The problem of simultaneous assignment of closed-loop eigenvalues and eigenvectors using constant complete state-feedback controller is discussed. It is shown that for a given nth-order multivariable system not necessarily completely controllable, associated with every point.

Bounds for robust eigenvalue assignment in a sector

1997 European Control Conference (ECC), 1997
This paper deals with the research of robustness bounds for system matrices of linear state-space models. These bounds on unstructured uncertainties norm guarantee that the eigenvalues of the perturbed matrix keep on lying in a sector. Several bounds, obtained thanks to different approaches relevant whether to Lyapunov's theory or to the notion of ...

Controlling oscillation by noncritical eigenvalue assignment

1997 1st International Conference, Control of Oscillations and Chaos Proceedings (Cat. No.97TH8329), 2002
Linear feedback stabilization of nonlinear systems in critical cases (NSICC) is studied in this paper. The noncritical eigenvalues are assumed completely controllable. The stability and linear feedback stabilizability are attacked by means of center manifold method and Lyapunov stability analysis.

Single-Input Eigenvalue Assignment Algorithms: A Close Look

SIAM Journal on Matrix Analysis and Applications, 1998
A detailed comparison of the available computational algorithms for single-input pole assignment of linear control systems is presented. Several previously known backward stable QR-type algorithms are tied together in a common framework where each of the previous algorithms is a special case, and their connection to an explicit expression for the gain ...

Eigenvalue Assignment by Static Output Feedback

IFAC Proceedings Volumes, 1997
Abstract This paper investigates a new method for the search of a solution to the problem of eigenvalue assignment by means of static output feedback or, when there is no solution to this problem, for the synthesis of a minimal order controller that allows arbitrary pole placement.
