Enhancing navigation integrity for Urban Air Mobility with redundant inertial sensors
TL;DR: In this paper , the authors proposed a new approach to enhance navigation integrity for UAM by integrating multiple IMUs with GNSS, and the corresponding integrity monitoring algorithm is developed to detect the faults in GNSS and/or IMUs and evaluate the probabilistic upper bounds on navigation errors, namely protection levels.

Cascade attitude control of a quadcopter in presence of motor asymmetry
TL;DR: In this study, the problem of UAV attitude control is investigated when there are discrepancies in the characteristics of the 4 actuators, i.e., electrical motors and propellers, and a cascade control strategy is proposed with a PD controller in the inner loop to achieve stabilization, and PI controllers in the outer loop to ensure disturbance rejection.
