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. <br> <br> Collaborators: Liam S. P. L
 awrence (UWaterloo) and Enrique Mallada (JHU)
