Robust pole assignment in uncertainsystems
IEE Proceedings - Control Theory and Applications, 1997The concept of 'pole colouring' is introduced as a graphical aid to the problem of observing the closed-loop system pole variations as a function of uncertainty. Some possible cost functions that can be used to measure the performance robustness of the resulting systems are also considered.

Pole-assignment adaptive stabiliser
Proceedings of 2003 IEEE Conference on Control Applications, 2003. CCA 2003., 2004A fixed gain power system stabiliser is inadequate to provide acceptable damping characteristics as the operating point changes. For the first time in power system an adaptive Pole Assignment stabiliser is developed to overcome this problem by fixing the poles of the transfer function G/sub d/(s)=/spl Delta//spl delta///spl Delta/P/sub m/.

A Schur Approach to Pole Assignment Problem
IFAC Proceedings Volumes, 1981Abstract A new approach to the pole assignment in linear systems is proposed which is based on unitary or orthogonal transformation of the closed loop system matrix to its Schur canonical form. The method has a number of advantages over the other known methods. In particular it does not require the computation of the charac-teristic polynomial of the

This correspondence presents an alternative proof of the fact that if a linear time-invariant multivariable dynamical equation is controllable, then by introducing state-variable feedback the eigenvalue of the new A matrix can be arbitrarily chosen. The feature of the proof is the nonsingular transformation of the input vector.

Perturbation Analysis of the Pole Assignment Problem
SIAM Journal on Matrix Analysis and Applications, 1996An analysis which reveals the sensitivity of the state feedback matrix to perturbations in the system matrices and the set of desired poles in the pole assignment problem for linear systems is presented. The analysis is based on the implicit function theorem and its generalization and covers the case of distinct closed-loop poles only.

On pole structure assignment in linear systems
International Journal of Control, 2009The problem of pole structure assignment (PSA) by state feedback in implicit, linear and uncontrollable systems is discussed in the article. It is shown that the problem is solvable if the system is regularisable. Then necessary and sufficient conditions for characteristic polynomial assignment are established. In the case of PSA (invariant polynomials

A novel approach and some new algorithms for the pole-assignment problem of a controllable time-invariant linear multivariable system with linear state or output feedback are presented. The main theme of the approach and the algorithms is to satisfy some constraints in the problem approximately.

Regional pole assignment with eigenstructure robustness
International Journal of Systems Science, 1997The paper provides a computational procedure for a type of robust regional pole assignment problem. It allows closed-loop poles to be settled at certain perturbation insensitive locations within some prespecified regions in the complex plane. The novelty of our approach lies in the versatility of the proposed algorithm which provides a rick set of ...

A robust periodic pole assignment algorithm
IEEE Transactions on Automatic Control, 1995A robust periodic pole assignment algorithm for linear, time-invariant, discrete-time systems is proposed. The algorithm produces a state- feedback law able to assign a prescribed set of eigenvalues and to minimize the condition numbers of the eigenvector matrices of the closed- loop system.
