We show that second-order adaptation allows checking whether a (local) plant optimum is reached upon convergence. A sufficient convergence condition that is applicable to first- and second-order modifier-adaptation schemes is proposed. We also discuss how second-order updates can lead to SQP-like model-free RTO schemes. The approach is illustrated via the simulated example of a continuous reactor.en1474-6670201476227628ElsevierConvergenceHessian approximationModifier adaptationReal-time optimizationMathematicsConference Paper10.3182/20140824-6-za-1003.00735Conference Paper
