DESCRIPTION:The optimal steady-state control problem is that o
f designing a feedback controller for a multivaria
ble system which regulates selected system variabl
es to the solution of a constrained optimization p
roblem\, despite parametric modelling uncertainty
and unmeasured exogenous disturbances. For example
\, an instance of this problem occurs in the desig
n of secondary frequency control systems\, where c
ontrol resources should be optimally used subject
to the elimination of frequency deviations and res
toration of inter-area tie-line flows. We present
a constructive design framework that reduces the O
SS control problem to a more classical control pro
blem of output regulation (tracking and disturbanc
e rejection). Robustness issues which arise in the
constructive procedure are discussed\, leading to
a solution of the OSS control problem for the cas
e where the plant is LTI with structured parametri
c uncertainty and unknown disturbances are constan
t in time. We apply the results to frequency contr
ol of power systems show that the OSS control fram
ework recovers several recent decentralized and di
stributed secondary frequency controllers from the
literature.
