Jc. Geromel et al., H-2-norm optimization with constrained dynamic output feedback controllers: Decentralized and reliable control, IEEE AUTO C, 44(7), 1999, pp. 1449-1454
This paper addresses some open problems in the area of dynamic output feedb
ack control design. The first one is the structurally constrained decentral
ized control problem, and the second is related to robust and reliable cont
rol. A necessary and sufficient condition for decentralized and quadratic s
tabilizability is given and used to provide a solution to the H-2-norm opti
mization problem. A numerical cross decomposition algorithm is developed an
d satisfactorily applied to find the solution of some illustrative examples
. A comprehensive benchmark validates the results.
