Abstract:

We present a novel estimation approach for Airborne Wind Energy systems with ground-based control and energy generation. The estimator fuses measurements from an Inertial Measurement Unit attached to a tethered wing and position measurements from a camera as well as line angle sensors in an Unscented Kalman filter. We have developed a novel kinematic description for tethered wings to specifically address tether dynamics. The approach presented simultaneously estimates feedback variables for an autonomous flight controller as well as model parameters, such as a time-varying delay. We demonstrate the performance of the estimator for experimental flight data and compare it to a state-of-the-art estimator based on inertial measurements.
