Scilab Function

contr - controllability, controllable subspace

Sequence d'appel

[n [,U]]=contr(A,B [,tol])
[A1,B1,U,ind]=contr(A,B [,tol])

Parametres

Description

[n,[U]]=contr(A,B,[tol]) gives the controllable form of an (A,B) pair.(dx/dt = A x + B u or x(n+1) = A x(n) +b u(n)). The n first columns of U make a basis for the controllable subspace.

If V=U(:,1:n), then V'*A*V and V'*B give the controllable part of the (A,B) pair.

[A1,B1,U,ind]=contr(A,B) returns the Hessenberg controllable form of (A,B).
