Elementary Factors and Reduced Minors for Linear Systems over Commutative Rings
Kazuyoshi MORI
In 1994, Sule presented the necessary and sufficient conditions of the feedback stabilizability of systems over unique factorization domains in terms of elementary factors and in t…
A Parameterization of Stabilizing Controllers over Commutative Rings
Kazuyoshi Mori
We present a parameterization of the stabilizing controllers over commutative rings. In the classical case, that is, in the case where there exist the right-/left-coprime factoriza…
Feedback Stabilization over Commutative Rings with no Right-/Left-Coprime Factorizations
Kazuyoshi MORI
Anantharam showed in 1985 the existence of a model in which some stabilizable plants do not have its right-/left-coprime factorizations. In this paper, we give a condition of the n…
Feedback Stabilization over Commutative Rings: Further study of the coordinate-free approach
Kazuyoshi Mori, Kenichi Abe
This paper is concerned with the coordinate-free approach to control systems. The coordinate-free approach is a factorization approach but does not require the coprime factorizatio…
