Bounding the distance of a controllable and observable system to an uncontrollable or unobservable one
(1999)
Article
Open AccessLet $(A,B,C)$ be a triple of matrices representing a time-invariant linear system $\left .\aligned \dot x(t)&=Ax(t)+Bu(t)\\y(t)&=Cx(t)\endaligned \right \}$ under similarity equivalence, corresponding to a realization ... -
Bounding the distance of a controllable system to an uncontrollable one
(1998)
Article
Open AccessLet $(A,B)$ be a pair of matrices representing a time-invariant linear system $\dot x(t)=Ax(t)+Bu(t)$ under block-similarity equivalence. In this paper we measure the distance between a controllable pair of matrices ... -
