Claim One:
1. A method of controlling a system in accordance with an objective function J, the operation of said system being describable by an equation &Dgr;y&equals;G&Dgr;u, where y represents one or more system-controlled output variables, u represents one or more system-manipulated input variables, G represents system gain parameters, and where J is a function of G, said method comprising the steps of: (a) modeling said system according to an equation &Dgr;y&equals;{tilde over (G)}&Dgr;u, where {tilde over (G)} is a nominal estimate of G and has a known uncertainty description and where {tilde over (J)} is said objective function J applied to {tilde over (G)}; and (b) computing steady-state targets for said system-manipulated variables u including extremizing said objective function J cast as a quadratic program, such that all of said system-controlled variables will remain feasible at steady-state for all possible values of the system parameters within said known uncertainty description.
