Abstract:We exploit the first-order aerodynamic effects for the feedback control of quadrotors in order to enhance the performance of the closed-loop system. We describe first the origin of these forces and then we show how the complexity of the system dynamics can be transformed by a change of control input into a simpler form, for which the classical hierarchical control approach (slightly modified here) can be applied. The simulation results illustrate the soundness of the proposed drag-augmented control scheme.

This paper addresses the path following control problem for scale-model fixed-wing aircraft. Kinematic guidance and dynamic control laws are developed within a single coherent framework that exploits a simple generic model of aerodynamic forces acting on the aircraft and applies to almost all regular 3D paths. The proposed control solutions are derived on the basis of theoretical stability and convergence analyses. They are complemented by addressing several practical issues, and validated via realistic hardware-in-the-loop simulations.

This paper describes a new control approach for scale-model airplanes. The proposed control solution is primarily geared towards drones whose lift surfaces can be approximated by a disc-shaped wing. Designed and analysed on the basis of a specific model of aerodynamic forces acting on the aircraft, it departs from other solutions in its capacity to handle important and rapidly changing attack angles within a large flight envelope. Simulation results illustrate its robust performance.
