Riccati solver with hamiltonian matrices as inputs.
In the continuous time case, the syntax is ric_descr(H)
(one input):
Riccati equation is:
Defining the hamiltonian matrix H
by:
with the syntax [X1,X2,zero]=ric_descr(H)
, the
solution X
is given by X=X1/X2
.
zero
= L1 norm of rhs of (Ec
)
The solution X
is also given by X=riccati(A,Q,R,'c'))
In the discrete-time case, the syntax is ric_descr(H,E)
(two inputs):
The Riccati equation is:
Defining G=B/R*B'
and the hamiltonian pencil (E,H)
by:
with the syntax [X1,X2,err]=ric_descr(H,E)
, the
solution X
is given by X=X1/X2
.
zero
= L1 norm of rhs of (Ed
)
The solution X
is also given by X=riccati(A,G,C,'d')
with G=B/R*B'
