Active fault-tolerant control for a quadrotor helicopter against actuator faults and model uncertainties
TLDR
The effectiveness of the proposed active fault-tolerant control strategy is validated through real experiments based on a quadrotor helicopter subject to actuator faults and model uncertainties and its advantages are demonstrated in comparison with a model-based fault estimator and a conventional adaptive sliding mode control.About:

Unknown input observer-based appointed-time funnel control for quadrotors
TL;DR: In this article , an unknown input observer-based appointed-time funnel control policy is proposed for quadrotors suffering from environmental disturbances and parametric uncertainties, where a continuous piecewise function is embedded to specify the funnel envelop, such that the stringent temporal constraints can be arbitrarily prescribed by operators.
