AN ALGORITHM FOR THE SINGLE-INPUT POLE ASSIGNMENT PROBLEM

B. N. Datta and K. Datta have proposed an efficient parallel algorithm for the single-input pole assignment problem when the spectrum set to be assigned is pairwise distinct and disjoint from the spectrum of th e dynamical matrix. This paper first presents a theoretical analysis o f that algorithm and then presents the necessary modifications on it f or an arbitrary spectrum. Based on the modified algorithm, the authors present two new algorithms for the problem and give some results on c ontrollability that are of independent interests.
