Modifier-Adaptation Schemes Employing Gaussian Processes and Trust Regions for Real-Time Optimization ⁎ ⁎ The first two authors contributed equally to the paper

This paper investigates modifier-adaptation schemes based on Gaussian processes to handle plant-model mismatch in real-time optimization of uncertain processes. Building upon the recent work by Ferreira et al. [European Control Conference, 2018], we present two improved algorithms that rely on trust-region ideas in order to speed-up and robustify the approach. The first variant introduces a conventional trust region on the input variables, …
