Airborne Seeker Application in Three Dimensional Formation Flight of UAVs

This paper deals with the leader-follower formation control problem while communication constraint in data transmitting is considered. From a practical point of view, we study the case in which unmanned vehicles are subject to the limited sensing, and communication is of a particular interest. A three-dimensional formation flight of multi-unmanned aerial vehicles with leader-follower configurat...

Minimum - Energy Flight Paths for Uavs Using

Near-obstacle flight with small UAVs∗

Autonomous flight in confined or cluttered environments such as houses or urban canyons requires high manoeuvrability, fast mapping from sensors to actuators and very limited overall system weight. Although flying animals are well capable of solving this problem, roboticists have difficulties at reproducing such capabilities. This paper describes why and how we took inspiration from flying inse...

Randomized Algorithm for UAVs Group Flight Optimization

The problem of small UAVs flight optimization is considered. To solve this problem thermal updrafts are used. For the precise detection of the thermal updrafts center the simultaneous perturbation stochastic approximation (SPSA) type algorithm is proposed. If UAVs use thermal updrafts so they can save the energy during the flight. Therefore the flight time will be vary for different UAVs. In or...

Nonlinear Control of Stabilized Flight and Landing for Quadrotor UAVs

Quadrotor UAVs are one of the most preferred type of small unmanned aerial vehicles because of the very simple mechanical construction and propulsion principle. However, the nonlinear dynamic behavior requires a more advanced stabilizing control and guidance of these vehicles. In addition, the small payload reduces the amount of batteries that can be carried and thus also limits the operating r...
