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