gamitg

H-infinity gamma iterations

Calling Sequence

[gopt]=gamitg(G,r,prec [,options]);

Arguments

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 dimensions 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.
