LPV Modeling of a Flexible Wing Aircraft Using Modal Alignment and Adaptive Gridding Methods.
TLDR
The notion of σ-shifted and [Formula: see text]-norm are introduced and used as a metric to measure the model mismatch and a new modal alignment algorithm is developed which utilizes the defined metric for aligning all the local models over the entire gridded parameter space.About:
