.SH NAME
ccontrg - central H-infinity controller
.SH CALLING SEQUENCE
.nf
[K]=ccontrg(P,r,gamma);
.fi
.SH PARAMETERS
.TP
P
: \fVsyslin\fR list (linear system in state-space representation)
.TP
r
: 1x2 row vector, dimension of the 2,2 part of \fVP\fR
.TP
gamma
: real number
.SH DESCRIPTION
returns a realization \fVK\fR of the central controller for the
general standard problem in state-space form.
.LP
Note that gamma must be > gopt (ouput of \fVgamitg\fR)
.LP
P contains the parameters of plant realization \fV(A,B,C,D)\fR
(\fVsyslin\fR list) with
.nf
B = ( B1 , B2 ) , C= ( C1 ) , D = ( D11 D12)
( C2 ) ( D21 D22)
.fi
\fVr(1)\fR and \fVr(2)\fR are the dimensions of \fVD22\fR (rows x columns)
