fspec

spectral factorization of continuous time dynamical systems

Syntax

gm=fspec(g)

Arguments

g

a continuous time linear dynamical system.

gm

a continuous time linear dynamical system.

Description

returns gm with gm and gm^-1 stable such that:

g = gtild(gm)*gm

gtild(gm) returns a state-space representation of gm(-s)'.

g is inversible.

Imaginary-axis poles are forbidden.

gtild(g)=g (poles and zeros of g are symmetric wrt imaginary axis).

g(inf) is positive definite.

Examples

a=-1000;
b=5;
c=5;
d=5;
sl=syslin('c',a,b,c,d);
fspec(sl)
