Tilt-rotor multivariable attitude control with rotor state feedback
In this paper, a multi-objective optimization-based methodology for rotorcraft attitude control law design is applied to a tilt-rotor case; the framework allows to enforce requirements of stability, performance, control action moderation, and safety.

The tilt tri-rotor unmanned aerial vehicle (UAV) has three flight modes: the hover mode, the transition mode, and the fixed-wing mode. Controller design in the hover mode is the premise of realizing stable flight of this kind of UAV.

Aeroelastic optimization of a composite tilt rotor
Composite tilt rotor aeroelastic optimization is performed by using a mixed variational formulation based on exact intrinsic equations of motion for moving beams and a finite-state dynamic inflow theory. A composite box-beam model is used to represent the principal load carrying member of the rotor blade. The blade is discretized using finite elements.
