Title: Controllers that determine optimal tuning parameters for use in process control systems and methods of operating the same

Abstract: The present invention provides a processing system that is capable of achieving substantially optimal control performance of a process facility on a "worst case" process system by accounting for changing system dynamics. The processing system includes a storage device and a processor. The storage device is operable to represent (i) at least one of a plurality of associated processes mathematically to define the various relationships among different inputs and outputs of the one or more represented associated processes, and (ii) uncertainty factors that are associated with these defined relationships. The uncertainty factors define a range of dynamics across which the one or more represented associated processes operate, an error in the mathematical representation, or, alternatively, some combination of the same. The processor is responsive to the mathematical representation and the uncertainty factors and is capable of determining tuning parameters for use by the control system to control the one or more represented associated processes and thereby cooperate to optimize said process facility.
