Modeling and control of a quadrotor UAV with tilting propellers [PDF]
Standard quadrotor UAVs possess a limited mobility because of their inherent underactuation, i.e., availability of 4 independent control inputs (the 4 propeller spinning velocities) vs. the 6 dofs parameterizing the quadrotor position/ orientation in space.

Geometric controls for a tethered quadrotor UAV [PDF]
This paper deals with the dynamics and controls of a quadrotor unmanned aerial vehicle that is connected to a fixed point on the ground via a tether. Tethered quadrotors have been envisaged for long-term aerial surveillance with high-speed communications.

A novel emergency controller for quadrotor UAVs
In this paper, an emergency controller is developed for AscTec Pelican quadrotor suffering a severe failure in one of its motors or rotors. With one of its motors badly damaged, it is impossible to perform the control of a quadrotor using old control strategies or conventional fault tolerant control techniques. The emergency controller designed in this

Safety Control for the Quadrotor Unmanned Aerial Vehicle Despite Complete Lose of One Rotor
This paper focus on the fault tolerance control associated with complete loss of controller one rotor for the quadrotor unmanned aerial vehicle(UAV). As the quadrotor UAV is widely used in many industrial filed, it is critical to ensure the safety flight
