Transition times using different optimization strategies; two distinct caseof uncertainty are considered, each with different initial conditions corresponding todifferent solvent concentrationsCase Robust solution NCO tracking Num. optimization(uncertainty known) (uncertainty unknown) (uncertainty known)nominal ≥ 5 1.008 1.0uncertainty 1 ≥ 5 2.03 1.81uncertainty 2 ≥ 5 0.938 0.915contrast, NCO tracking comes very close to the best possible solution, withoutknowledge of the uncertainty but at the expense of on-line measurements and(possibly) state estimations.The results have demonstrated that a simple decentralized control strategyusing a solution model and measurements can implement a complex grade transition.It must be re-emphasized that the generation of the solution model aswell as its superstructure requires the optimal solution for the nominal case andprocess insights that help to simplify it. However, the economic benefits in termsof transition time reduction, and thus the amount of off-spec material, is quitesignificant compared to the conventional approach practiced in the plant. Forlimited grade transitions, nominal optimal solutions can be calculated off-lineand implemented on-line using NCO tracking controllers. However, reliable onlinemeasurements or model-based estimates of certain variables are required.Furthermore, the solution model has to be tested and validated for differentrealization of uncertainty as an online re-optimization is not considered.5 ConclusionsIn this contribution, it is emphasized that the scope of NMPC needs to bebroadened from its classic roles of set-point tracking and disturbance rejection.In the context of real-time business decision making (RT-BDM) implemented
Integration of Economical Optimization and Control 433in the automation hierarchy, a cascaded optimizing feedback control strategy isnecessary for economical and agile plant operation. A two-level decompositionstrategy of dynamic optimization and control of transient processes is suggested.The overall objectives of profitability and flexibility with respect to scheduledor un-scheduled transitions are maintained consistently at two optimization andcontrol levels. For tighter integration and effective uncertainty handling, two approachesbased 1) on neighboring extremal control with inequality constraintsand 2) on decentralized control for tracking the necessary conditions of optimalityof the economical optimization problem are used. The simulated industrialapplications for different transitions have shown significant economical benefits.The case studies show the potential of the suggested approaches. Obviously, thereare many opportunities for the further development of an integrated dynamicoptimization and control system implemented in multiple levels that consistentlysolves simple level-specific problems as part of the automation hierarchy.References[1] T.
