gamitg(5) Scilab Function gamitg(5)
NAME
gamitg - H-infinity gamma iterations
CALLING SEQUENCE
[gopt]=gamitg(G,r,prec [,options]);
PARAMETERS
G : syslin list (plant realization )
r : 1x2 row vector (dimension of G22)
prec : desired relative accuracy on the norm
option : string 't'
gopt : real scalar, optimal H-infinity gain
DESCRIPTION
gopt=gamitg(G,r,prec [,options]) returns the H-infinity optimal gain gopt.
G contains the state-space matrices [A,B,C,D] of the plant with the usual
partitions:
B = ( B1 , B2 ) , C = ( C1 ) , D = ( D11 D12)
( C2 ) ( D21 D22)
These partitions are implicitly given in r: r(1) and r(2) are the dimen-
sions of D22 (rows x columns)
With option='t', gamitg traces each bisection step, i.e., displays the
lower and upper bounds and the current test point.
