In this paper, a new integrated control system via visual-servoing and cascaded proportional derivative (PD) controllers for an autonomous hexacopter is proposed. The spherical image based visual servoing is designed to control the hexacopter to the desired pose with respect to an arbitrary target in three-dimensional (3D) workspace based on images captured. Meanwhile, the cascade-PD controller is...
A position tracking controller for a hexacopter is presented which is robust against disturbances like modeling errors or propulsion efficiency degradation. The presented controller stands out because of its simple design which does not resort to reconfiguration and avoids the necessity of a Failure Detection and Isolation (FDI) filter. The baseline controller has a cascaded structure with two loops...
Wind turbine generators represent a valid and sustainable alternative for a significant energy provision, which is increasingly demanded by the planet, and a number of generator models have been proposed for supporting their design. However, equatorial regions have very special conditions for their gravity and wind behavior. Therefore, we present here a new wind turbine-generator model suitable for...
