nehari

Nehari approximant of continuous time dynamical systems

Syntax

[x]=nehari(R [,tol])

Arguments

R

a continuous time linear dynamical system in state-space representation.

x

a continuous time linear dynamical system in state-space representation.

tol

optional threshold, default value is 1e-6.

Description

[x]=nehari(R [,tol])returns the Nehari approximant of R.

R = linear system in state-space representation (syslin list).

R is strictly proper and - R~ is stable (i.e. R is anti stable).

|| R - X ||oo = min || R - Y ||oo
              Y in Hoo

History

VersionDescription
5.4.0 Sl is now checked for continuous time linear dynamical system. This modification has been introduced by this commit
