Doubly coprime factorization revisited
In this note, we derive a state-space formula for all proper linear Lime-invariant (I,TI) doubly coprime factorizations of a given LTI plant. As an application, we present a new derivation of the state-space formula for parameterization of all proper LTI stabilizing controllers.
