ccontrg(5)                     Scilab Function                     ccontrg(5)
NAME
  ccontrg - central H-infinity controller

CALLING SEQUENCE
  [K]=ccontrg(P,r,gamma);

PARAMETERS

  P    : syslin list (linear system in state-space representation)

  r    : 1x2 row vector, dimension of the 2,2 part of P

  gamma
       : real number

DESCRIPTION
  returns a realization K of the central controller for the general standard
  problem in state-space form.

  Note that gamma must be > gopt (ouput of gamitg)

  P contains the parameters of plant realization (A,B,C,D) (syslin list) with
  B = ( B1 , B2 ) ,        C= ( C1 ) ,    D = ( D11  D12)
                              ( C2 )          ( D21  D22)
  r(1) and r(2) are the dimensions of D22 (rows x columns)
