Zusammenfassung der Projektergebnisse

The development of a strategy for efficient combination of modifier adaptation with model adaptation in iterative real-time optimization was presented. We demonstrated a parameter selection procedure based on a local sensitivity analysis as suggested in the initial proposal of the project. The method selects the most influential parameters from a given set in order to improve the performance of the proposed approach. Finally, the MAWQA method for robust iterative real-time optimization was combined with parameter estimation with EMA. The main objective of the project was to develop a reliable and efficient RTO scheme that is robust with respect to the structural deficiencies of the plant model and in the presence of measurement noise. It was illustrated using a fed-batch reactor as a case study that the proposed methods ensure the convergence to the true plant optimum and achieve fast convergence.
