A method and apparatus for steady-state target calculation that explicitly accounts for model uncertainty is disclosed. In accordance with one aspect o f the invention, when model uncertainty is incorporated, the linear program associated with the steady-state target calculation can be recast as a highl y structured nonlinear program. In accordance with another aspect of the invention, primal-dual interior point methods can be applied to take advanta ge of the resulting special structure. For a system having characteristic gain parameters G having a known uncertainty description, the present invention provides a method and apparatus for selecting steady-state targets for said system-manipulated variables such that all system-controlled variables will remain feasible at steady-state for all possible values of the parameters G within the known uncertainty description. A nominal estimate G of the system parameters G is made, and in accordance with another aspect of the invention , the steady-state targets are selected such that when G=G, the system is driv en to an operational steady-state in which the objective function is extremized .
