fstabst
Youla's parametrization of continuous time linear dynamical systems
Syntax
J = fstabst(P, r)
Arguments
- P
a continuous time linear dynamical system.
- r
1x2 row vector, dimension of
P22
- J
a continuous time linear dynamical system (with same representation as
P
.
Description
Parameterization of all stabilizing feedbacks.
P
is partitioned as follows:
P=[ P11 P12; P21 P22]
(in state-space or transfer form: automatic conversion in state-space is done for the computations)
r
= size of P22
subsystem, (2,2) block of P
J =[J11 J12; J21 J22]
K
is a stabilizing controller for P
(i.e. P22
) iff
K=lft(J,r,Q)
with Q
stable.
The central part of J
, J11
is the lqg regulator for P
This J
is such that defining T
as the 2-port lft
of P
and J
: [T,rt]=lft(P,r,J,r)
one has that T12
is inner
and T21
is co-inner.
