gcare
Continuous time control Riccati equation
Syntax
[X, F] = gcare(Sl)
Arguments
- Sl
a continuous time linear dynamical system in state-space representation
- X
symmetric matrix
- F
real matrix
Description
Generalized Control Algebraic Riccati Equation (GCARE).
X
= solution , F
= gain.
The GCARE for Sl=[A,B,C,D]
is:
(A-B*Si*D'*C)'*X+X*(A-B*Si*D'*C)-X*B*Si*B'*X+C'*Ri*C=0
where S=(eye()+D'*D)
, Si=inv(S)
, R=(eye()+D*D')
, Ri=inv(R)
and F=-Si*(D'*C+B'*X)
is such that A+B*F
is stable.
