Nested modifier-adaptation for RTO in the otto williams reactor
D Navia, G Gutiérrez, C de Prada - IFAC Proceedings Volumes, 2013 - Elsevier
This paper deals with the problem of uncertainty management in real time optimization
(RTO). It proposes a new architecture in the modifier-adaptation methodology, reformulating
the algorithm as a nested optimization problem with two layers. Using this approach, it is
possible to find a point that satisfies the KKT conditions of a process using an inaccurate
model, but unlike the original modifier method, with no need to estimate the experimental
gradients of the process. The proposed method has been tested in the Otto Williams Reactor …
