Şefik, A.Sezer, M. E.2016-02-082016-02-0819910020-7179http://hdl.handle.net/11693/26185Based on the structure of a closed-loop system under a specified feedback pattern, a qualitative analysis of the problem of pole assignability is considered. The problem is first formulated algebraically, in terms of the relation p = g(f) between the vector p of the closed-loop characteristic polynomial coefficients and the vectorf of the non-zero elements of the feedback matrix. Then, translation to the structural framework is achieved by means of two theorems which give graph-theoretical sufficient conditions for solvability. These structural conditions also guarantee genericity of pole assignability. © 1991 Taylor and Francis Ltd.EnglishMathematical Techniques--Poles and ZerosMathematical Techniques--PolynomialsMathematical Techniques--VectorsClosed-Loop SystemFeedback MatrixPole Assignment ProblemPolynomial CoefficientsSpecified Feedback SystemControl SystemsArticle10.1080/00207179108934195
