Matrix eigenvalue spectrum assignment for linear control systems by static output feedback

, 2021
For a linear time-invariant control system defined by a linear differential equation of the n-th order with a multidimensional state, input and output, we set and study the problem of arbitrary matrix eigenvalue spectrum assignment by linear static ...

Robust Eigenvalue Assignment Techniques for the Sliding Mode

IFAC Proceedings Volumes, 1991
Abstract The assignment of the closed-loop eigenvalues of a Variable structure Control (VSC) System is discussed. In most VSC design approaches all of the closed-loop eigenvalues are directly assigned, however in many applications it may be desirable to simply assign eigenvalues which lie within a certain specified region of the complex plane.

On The Computation Of Eigenvalue Assignment Problem

1988 American Control Conference, 1988
This note shows that in computing the feedback gain for eigenvalue assignment in multivariable systems, the reduction of the condition number of the closed loop eigenvector matrix (CLEM) is a necessary step to achieve some highly important and desirable technical and computational properties.

Eigenvalue Assignment in Compensated Parameter Identifiers

1986 American Control Conference, 1986
The purpose of this paper is to utilize a class of compensated parameter identifiers for generating bias-free parameter estimates, in the presence of noise disturbance which accounts for the uncertainties in the system. A forward feedback is used to minimize the effect of noise.

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

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.

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 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.

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.
