Syntax
[k,gfin,stat] = hinfsyn(p,nmeas,ncon,gamma,{keywords})
Parameter Li st
Inputs: p Generalized interconnection structure (Dynamic Sys-
tem)
nmeas measurement vector dimension.
ncon control vector dimension.
gamma H∞norm bound of controller. For a bisection search spec-
ify gamma = [gamma min;gamma max].
Keywords: schur solution real Schur decomposition for Riccati solution (default)
eig solution eigendecomposition for Riccati solution.
tol tol=value. Specifies the relative tolerance for stopping a
bisection fit. Default = (gamma max - gamma min)/50
epr epr= value. Tolerance for determining when the Hamilto-
nianeig envalueslie on the jω axis. Default= 0.5*sqrt(eps)
epp epp = value. Tolerance for determining that a Riccati
equation solution is positive definite. Default = 1e-6
maxit maxit = value. Maximum number of bisection iterations.
Default = inf.
Outputs: k Central H∞optimal controller.
gfin H∞norm achievedfor the returned controller.
stat returnstatus
0 Controller calculated
-1 no controller exists for specified gamma value.
