h_cl - closed loop matrix
Calling Sequence
-
[Acl]=h_cl(P,r,K)
-
[Acl]=h_cl(P22,K)
Parameters
-
P, P22
: linear system (
syslin
list), augmented plant or nominal plant respectively
-
r
: 1x2 row vector, dimensions of 2,2 part of
P
(
r=[rows,cols]=size(P22)
)
-
K
: linear system (
syslin
list), controller
-
Acl
: real square matrix
Description
Given the standard plant
P
(with
r=size(P22)
) and the controller
K
, this function returns the closed loop matrix
Acl
.
The poles of
Acl
must be stable for the internal stability
of the closed loop system.
Acl
is the
A
-matrix of the linear system
[I -P22;-K I]^-1
i.e.
the
A
-matrix of
lft(P,r,K)
