contrss

Scilab Function

contrss - controllable part

[slc]=contrss(sl [,tol])

sl : linear system (syslin list)
tol : is a threshold for controllability (see contr). default value is sqrt(%eps).

returns the controllable part of the linear system sl = (A,B,C,D) in state-space form.

A=[1,1;0,2];B=[1;0];C=[1,1];sl=syslin('c',A,B,C);  //Non minimal
slc=contrss(sl);
sl1=ss2tf(sl);sl2=ss2tf(slc);      //Compare sl1 and sl2
