Parametrization of Stabilizing Controllers, Factorization Approach, Linear Systems


This paper presents a parametrization method of stabiliz ing controllers in the framework of the factorization ap proach. The result of this paper does not assume the ex istence of the coprime factorizability of plants. Under this condition, the number of parameters of the method is less than or equal to that of the previous ones. Further the result is a uniļ¬cation of the previous parametrization methods. This paper employs neither the localization nor the local global principle which need the knowledge of abstract al gebras.
