Youla's parametrization of continuous time linear dynamical systems
J = fstabst(P,r)
a continuous time linear dynamical system.
1x2 row vector, dimension of
a continuous time linear dynamical system (with same representation as
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
J =[J11 J12; J21 J22]
K is a stabilizing controller for
The central part of
J11 is the lqg regulator for
J is such that defining
T as the 2-port
[T,rt]=lft(P,r,J,r) one has that
T12 is inner
T21 is co-inner.
