des2tf
descriptor to transfer function conversion
Calling Sequence
[S]=des2tf(sl) [Bfs,Bis,chis]=des2tf(sl)
Arguments
- sl
list (linear system in descriptor form)
- Bfs, Bis
two polynomial matrices
- chis
polynomial
- S
rational matrix
Description
Given the linear system in descriptor form i.e.
Sl=list('des',A,B,C,D,E)
, des2tf
converts sl
into
its transfer function representation:
S=C*(s*E-A)^(-1)*B+D
Called with 3 outputs arguments des2tf
returns
Bfs
and Bis
two polynomial matrices, and chis
polynomial such that:
S=Bfs/chis - Bis
chis
is the determinant of (s*E-A)
(up to a xcative constant);
