This paper presents an approach to estimate wind vector for a micro UAV by using only its inertial measurement unit in real-time. This method does not need additional sensors and dedicated anemometer, while just relying on the onboard inertial measurement unit to reserve the valuable payload for other onboard sensors. A smoothing filter is also designed based on the minimum summation of distance vector...
A fault-tolerant cooperative control (FTCC) strategy for cooperative unmanned aerial vehicles (UAVs) used in forest monitoring, fire detection and tracking is investigated in this paper. The proposed algorithm solves the problem of monitoring and detection of forest fires, even when fault occurs to one or more UAVs. During the search stage, the UAVs team moves in a certain formation shape, a distributed...
In order to solving the problem in sampling period selection and frequency diversity reservation during real-time wind field estimation, a method of variable-frequency wind field information extraction is put forward based on small-window sliding Fourier transform. Firstly, a discrete wind information extraction method is proposed and used in the estimation. Secondly, for purpose of reducing the processing...
This paper presents new algorithms for distributed deployment of a network of multi-agent systems to minimize prescribed cost function. It is assumed that the so-called “operation cost” of distinct agents can be different. The problem is investigated for both cases of an obstacle-free environment and a fixed-obstacle environment. For the former case, the center multiplicatively weighted Voronoi (CMWV)...
