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 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.
