rncf
Description
computes
the right normalized coprime factorization of the dynamic system model
fact
= rncf(sys
)sys
. The factorization is given by:
Here, denotes the conjugate of Mr (see
ctranspose
).
The returned model fact
is a minimal state-space realization of the
stable system
[Mr;Nr].
This factorization is used in other normalized coprime factor computations such as model
reduction (ncfmr
) and controller synthesis (ncfsyn
).

fact
is a minimal realization of[Mr;Nr]
. If you need to use[Mr;Nr]
or[Mr;Nr]'
in a computation, it is better to usefact
than to concatenate the factors yourself. Such manual concatenation results in extra (nonminimal) states, which can lead to decreased numerical accuracy.
