Active Directional Modifier Adaptation with Trust Region - Application to Energy-Harvesting Kites

Dominique Bonvin, Colin Neil Jones, Martand Singhal, Matthieu Jonin, Sanket Sanjay Diwale

Many real-time optimization schemes maximize process performance by performing a model-based optimization. However, due to plant-model mismatch, the model-based solution is often suboptimal. In modifier adaptation, measurements are used to correct the mode ...
