State Estimation and Kalman Filtering of Tethered Airfoils: by use of ground based meausrments
Abstract
This thesis contains modeling, observability analysis and state estimator design of a tethered airfoil. A existing model is extended to include wind as a state and the wind is modeled. The observability analysis shows that the system is indeed observable. The choice of state estimator is evaluated and the UKF is found to achieve best results during simulations.
