dtsi

Arguments

G

a continuous time linear system.

Ga

a continuous time linear system antistable and strictly proper.

Gs

a continuous time linear system stable and strictly proper.

Gi

real matrix (or polynomial matrix for improper systems)

tol

optional parameter for detecting stables poles. Default value: 100*%eps

Description

returns the stable-antistable decomposition of G:

G= Ga + Gs + Gi, (Gi = G(oo))

G can be given in state-space form or in transfer form.

Ga and Gs are returned in the same representation (transfer function or state-space) than G.
