Abstract: In this study, a robust extended Kalman filter (EKF) for estimation of a spacecraft’s position and velocity by single station antenna tracking data against the effect of measurement matrix singularity is proposed. The ...

Abstract: In this paper, an active fault-tolerant flight control system against sensor/actuator failures for unmanned aerial vehicles (UAVs) is proposed. First, an approach to detecting and isolating UAV sensor failures affecting ...

Abstract: This study introduces a robust Kalman filter (RKF) with a filter-gain correction for cases of measurement malfunctions. Using defined variables called measurement-noise scale factors, the faulty measurements are taken into ...

Abstract: In this work, the adaptation of the process noise covariance matrix for the nontraditional attitude filtering technique is discussed. The nontraditional attitude filtering technique integrates the unscented Kalman filter ...

Abstract: Flight in all weather conditions has necessitated correctly detecting icing and taking reasonable measures against it. This work aims at the detection and identification of airframe icing based on statistical properties ...

Abstract: This study discusses simultaneous adaptation of the process and measurement noise covariance matrixes for a nontraditional attitude filtering algorithm. The nontraditional attitude filtering algorithm integrates the singular ...
