colregul

removing poles and zeros at infinity

Syntax

[Stmp, Ws] = colregul(Sl, alfa, beta)

Arguments

Sl,Stmp

syslin lists

alfa,beta

reals (new pole and zero positions)

Description

computes a prefilter Ws such that Stmp=Sl*Ws is proper and with full rank D matrix.

Poles at infinity of Sl are moved to alfa;

Zeros at infinity of Sl are moved to beta;

Sl is assumed to be a left invertible linear system (syslin list) in state-space representation with possibly a polynomial D matrix.
